Was nützt der beste Stromspeicher, wenn im Falle eines Blackouts das Haus dunkel bleibt? In Expertenforen wird oft hitzig über echten Ersatzstrom diskutiert – der SAX Netzumschalter NXZB-63H ist die technische Antwort auf diese Sicherheitsfrage. Als vollautomatische Umschalteinrichtung (ATS - Automatic Transfer Switch) ist er das Herzstück der SAX Notstrom-Lösung. Er überwacht permanent das öffentliche Netz und sorgt bei einem Ausfall für die lebenswichtige allpolige Trennung. Erst durch diese physische Entkopplung darf der SAX-Speicher sein Inselnetz aufbauen, ohne Techniker im öffentlichen Netz zu gefährden oder wertvolle Energie in ein totes Netz zu speisen.

Ihre Vorteile

Sicherheit und Automatisierung auf VDE-Niveau

Vollautomatische Umschaltung: Sie müssen nicht in den Keller laufen und Hebel umlegen. Der NXZB-63H erkennt den Netzausfall autonom und schaltet in Millisekunden um.

Allpolige Trennung (4-polig): In Deutschland zwingend vorgeschrieben für den Ersatzstrombetrieb. Er trennt nicht nur die drei Phasen (L1, L2, L3), sondern auch den Neutralleiter (N), um gefährliche Rückspeisungen und Potenzialverschleiß zu verhindern.

Hohe Schaltkapazität: Mit 63A Bemessungsstrom ist der Umschalter perfekt für Standard-Hausanschlüsse dimensioniert und bietet ausreichend Reserven für Wärmepumpen und Wallboxen im Netzbetrieb.

Kompakte Hutschienenmontage: Trotz seiner massiven Schaltleistung passt der NXZB-63H in Standard-Verteilerkästen und spart wertvollen Platz bei der Installation.

Mechanische Verriegelung: Ein internes Sicherheitssystem verhindert physikalisch, dass beide Stromquellen (Netz und Speicher) gleichzeitig aufgeschaltet werden können – ein Kurzschlussrisiko ist damit ausgeschlossen.

Kompatibilität

Der NXZB-63H ist primär als zertifizierte Komponente für das SAX Power Notstrom-System (Home 5.8 / Pulse 7.7) vorgesehen. Er arbeitet eng mit der SAX-Steuerelektronik zusammen, um die Synchronisation beim Wiederzuschalten des öffentlichen Netzes zu gewährleisten.

  • Systemintegration: Der Umschalter wird zwischen dem Hauptzähler und der Hausverteilung platziert.
  • Steuerspannung: Die Umschaltlogik wird direkt über die anliegenden Spannungsquellen versorgt, sodass keine externe Batterie für den Schaltvorgang nötig ist.
  • Phasen-Logik: Er unterstützt die vollständige Trennung des 3-Phasen-Systems, was für den sicheren Betrieb des einphasig einspeisenden SAX-Speichers im Ersatzstromfall (auf der Notstromphase) essenziell ist.

Lieferumfang

  • 1x Automatischer Umschalter NXZB-63H
  • Bedienungs- und Installationsanleitung
  • Anschluss-Schema für SAX Power Systeme

Garantie

Der Netzumschalter unterliegt der gesetzlichen Gewährleistung. Da es sich um eine elektromechanische Komponente für industrielle Anwendungen handelt, ist er auf extreme Langlebigkeit ausgelegt. Bei fachgerechter Installation in einer belüfteten Unterverteilung ist die mechanische Lebensdauer auf Jahrzehnte ausgelegt.

FAQ

Frage: Warum ist eine 4-polige Trennung durch den NXZB-63H so wichtig?

Antwort: In Deutschland darf im Inselbetrieb keine Verbindung zwischen dem Neutralleiter des Versorgungsnetzes und dem Inselnetz bestehen (TN-S oder TT-System Logik). Der NXZB-63H trennt den N-Leiter mit, um gefährliche Potenzialverschleppungen und Fehlauslösungen des RCD (FI-Schalter) zu vermeiden.

Frage: Ist die Umschaltzeit von < 50ms unterbrechungsfrei?

Antwort: Nein, es ist keine USV (Unterbrechungsfreie Stromversorgung) im IT-Sinne. Ein Computer ohne Pufferkondensator könnte neu starten. Für Beleuchtung, Heizungspumpen, Kühlschränke und die meisten Haushaltsgeräte ist diese Zeit jedoch so kurz, dass sie den Ausfall kaum bemerken.

Frage: Kann ich den NXZB-63H auch für andere Wechselrichtermarken nutzen?

Antwort: Technisch ist es ein Standard-ATS-Bauteil. Die Zertifizierung und das Zusammenspiel der Hilfskontakte sind jedoch speziell auf die SAX Power Logik abgestimmt. Bei Fremdsystemen muss die Ansteuerung bauseits durch eine Elektrofachkraft geprüft werden.

Frage: Was passiert, wenn der Strom wiederkommt?

Antwort: Der NXZB-63H überwacht die Spannung am Netzeingang. Sobald diese wieder stabil anliegt, schaltet er (nach einer kurzen Sicherheitsverzögerung zur Netzstabilisierung) das Haus automatisch zurück auf das öffentliche Netz und der SAX-Speicher geht wieder in den normalen Lademodus über.

Frage: Darf ich den Umschalter selbst einbauen?

Antwort: Nein. Da der Einbau einen Eingriff in den Bereich vor und nach dem Zähler darstellt und sicherheitskritische Netzformen berührt, darf die Installation ausschließlich durch einen beim Netzbetreiber eingetragenen Elektroinstallateur erfolgen.

The start of this book had me nervous but I ended up really loving this book! I loved how aware Logan was to what he was doing to Grace and stopped it even though it hurt to read. I loved that Grace made him WORK for her forgiveness and some parts were even SO funny. I loved all four of the guys and their great banter. My sweet baby Logan really was going through it in his personal life and his story resonated so much with me. I cried multiple times while reading and cried happy tears at the ending. It was perfect and exactly how I hoped it would end. 🎧 The narrators did a fantastic job with the dual narration.

*MILD SPOILERS*
Format: Kindle
this was amazing!!! i loved the characters and the writing is a lot better than most of its sport-romance-book counterparts. the worst part of it for me was the climax, i felt as though the FMC’s actions did not match her personality type. he is unsure about their relationship and is worried that she will leave him due to the seemingly bleak and boring future ahead of him. he voices this to her and she gets mad. mind you, this man had to grovel and beg and complete tasks for a single DATE. like girl, if we had been dating for 2 months and i had to do all that to get a date, i would be insecure too. it was quick so easily ignorable, but still bumped it down a star.

The 1st one is better than this one but I still love it
Format: Kindle
The Mistake is the second book in Elle Kennedy’s Off-Campus series, following a new couple while maintaining the humor, steamy romance, and emotional depth that made The Deal so popular. This installment focuses on Logan, Garrett’s best friend and fellow hockey player, and Grace, a quiet but strong-willed freshman, as they navigate second chances and personal growth. John Logan – Logan is charming, funny, and a ladies' man, but beneath his confident exterior, he struggles with deep-seated family issues and a sense of being trapped by his circumstances. His development throughout the book makes him more than just the stereotypical player. Grace Ivers – A freshman who starts off shy but proves to be independent and assertive. She isn’t easily won over, and her ability to stand her ground makes her a refreshing and likable heroine. Familiar faces from The Deal, including Garrett and Hannah, return, while new side characters add to the college setting’s energy and humor. Kennedy’s writing is engaging, with a mix of humor, emotional moments, and steamy romance. The alternating perspectives between Logan and Grace allow for a well-rounded view of their relationship and personal struggles. The book delivers plenty of humor and flirty banter while also tackling deeper themes of family responsibility, self-worth, and making tough life choices. The chemistry between Logan and Grace is strong, and their romance is a blend of fun, tension, and genuine emotional connection. Strengths ✔ Strong Character Growth – Both Logan and Grace undergo realistic, satisfying development. ✔ Second-Chance Romance Done Right – Logan’s journey to making up for his mistake feels earned, and Grace doesn’t immediately forgive him, which adds authenticity. ✔ Engaging Writing & Humor – The witty dialogue and college setting keep the story entertaining. ✔ Balanced Romance & Personal Struggles – The love story is front and center, but each character also has their own challenges to overcome. The Mistake is a fun, emotional, and steamy addition to the Off-Campus series. While it follows a familiar formula, the engaging characters and well-paced romance make it a standout. Fans of The Deal and other college sports romances like The Chase by Elle Kennedy or The Score (book 3 in the series) will love this one.

I loved everything about The Deal by Elle Kennedy!
Format: Kindle
I have been a huge fan of Elle Kennedy’s writing for years. I loved her Out of Uniform series and Killer Instincts series. Her After Hours series is sizzling hot. She has a way of bringing her characters to life and making them demand your absolute attention. Her books have a combination of witty dialogue, dynamic characters, a well developed plot, and pacing that keeps the reader enthralled. Most of her books have either been erotic romance or romantic suspense. I was wondering how she would pull off a New Adult romance. New Adult romance is a generalized genre that can contain sweet & sexy, dark & intense, angsty & anxious, or exciting & erotic. The Deal has all of these elements and more. It is one of the most enjoyable and entertaining New Adult romances that I have read. I connected with the main characters as well as the secondary characters. They were all larger than life in their own way. The one thing that stood out besides the main characters romance was Elle’s portrayal of college life. She portrayed a very realistic look at life on the college campus and how it relates to their courses as well as social life. Garrett Graham is the bad boy of the college hockey team. He makes panties melt and owns his man whore reputation with relish. He has an overinflated ego that matches his cocky attitude. He is a star player and lives for playing hockey. He is diligent with his grades, practices, and performance. When he fails his philosophy mid term, it could not only ruin his GPA, it will affect his position on the team. He could lose the one thing he lives for. He is going to have to retake his philosophy mid term and ace it in order to remain on the team. He needs help. Who better to help him than one of the few students that managed not only to pass the mid term but ace it. He never really noticed Hannah Wells before until she accidentally dropped her exam and he saw her A. Now he is on a mission to get Hannah to tutor him. He will try to bribe her, entice her, and woo her. When he discovers the golden carrot that will make her give in, he will dangle it in every way he can. His life is counting on that golden carrot. Hannah Wells is a music major. She is a pretty confident and outgoing girl with her friends and peers. She is smart, personable, and resilient. She is dedicated to her craft. The one area she lacks in is her confidence with the opposite sex. She has finally found a guy that she is interested in and she has no clue how to deal with her attraction. Not only is he out of her league, he is also the star quarterback on the football team. Not the type of guy she would normally take an in interest in. She has had some very bad experiences with the opposite sex. Although she has mostly overcome her issues, she is still a bit leery and scared. If she can get past her fears, she may be able to approach him. When the ego maniac sex god, Garrett Grant, approaches her to tutor him in philosophy, she thinks he is out of his ever loving mind. There is no way she is going to tutor the self absorbed jock. That is until he finds out her ultimate weakness and offers her a guaranteed solution. His persistence and golden carrot are enough to make her cave. It’s time to make a deal with the Devil. Hannah and Garrett are in for some big surprises. They are both quite different than they appear on the surface. Hannah may have the upper hand when the tutoring begins but Garrett will quickly take control of the situation. Both will be in for a great learning experience. Both will come out winners in the end. Their Deal will seal both their fates. I loved the banter between Garrett and Hannah. The snarky sarcasm, witty comebacks, and dirty talking are beyond clever and entertaining. The heated bedroom scenes make your temperature burn out of control. The emotional and intimate moments will have you swooning. What I loved best is how they formed a deep respect and friendship with one another. They were able to honestly confide in one another and know that their trust was not misplaced. I loved everything about this book! Read The Deal by Elle Kennedy. I am looking forward to the next book in the Off-Campus series. The Mistake will release in June of 2015. It is a complete mystery of who this book will feature or what their story is about.

A Beloved College Romance That Earns Its Hype.
Format: Kindle, Format: Kindle
The Deal by Elle Kennedy is a college romance that fully delivers on its reputation. With engaging characters, steady emotional growth, and a relationship that develops naturally, it’s easy to see why this book remains so popular. The story follows Hannah Wells, a focused and reserved music student, and Garrett Graham, the confident captain of the college hockey team whose academic struggles threaten his future. When their paths cross through an unexpected agreement, a friendship begins that gradually deepens into something more meaningful. One of the book’s greatest strengths is its pacing. The relationship doesn’t rush or rely on instant attraction alone. Instead, it builds through shared experiences, honest conversations, and growing trust. This approach makes the connection between the characters feel believable and emotionally grounded. Both Hannah and Garrett face personal challenges that shape their decisions and growth throughout the story. These elements add depth without overwhelming the romance, keeping the focus on character development and mutual support. The dialogue is lively, the humour is well-placed, and the emotional moments are balanced with lighter scenes that keep the story moving. While some plot elements may feel familiar to readers of the genre, the overall execution is strong. The conflicts fit naturally within the story, and the resolution is satisfying without feeling overextended. The Deal is an enjoyable, well-written romance that blends heart, humour, and character-driven storytelling. A solid choice for readers who enjoy college settings, slow-burn relationships, and emotionally engaging narratives.
