Milesight CT303 Self-Powered 3-Phase 300A LoRaWAN Current Transformer

Revolutionize Your Energy Management

Introducing the Milesight CT303, a state-of-the-art LoRaWAN® Smart Current Transformer designed for precise, real-time monitoring of electrical consumption. Engineered for efficiency and accuracy, the CT303 is the ideal solution for smart building energy management, equipment performance monitoring, and predictive maintenance. Its innovative one-to-three design allows you to measure the electricity of up to three different objects simultaneously, providing comprehensive insights into your energy usage patterns to foster conservation and reduce operational costs.

Effortless Installation & Unmatched Performance

The CT303 features a user-friendly, non-invasive clamp-on design that ensures safe and rapid installation without the need to interrupt power or risk circuit damage. This cable-free deployment simplifies the process, reduces labor costs, and offers flexible placement. A standout feature is its self-powered technology; the device derives energy directly from the measured circuit, completely eliminating the need for batteries and ensuring continuous, seamless operation. With a high sampling frequency of up to 3.3kHz, the CT303 delivers superior accuracy (±1%), outperforming competitors and guaranteeing unparalleled detail in your energy data.

Smart Monitoring with Instant Alerts

Stay ahead of potential issues with intelligent threshold alerts. You can set minimum and maximum current thresholds and receive instant alarms when these are triggered. The over-current alert provides immediate notification when the current exceeds the rated limit, accompanied by a flashing LED indicator for quick visual confirmation. For enhanced safety, an optional external wire temperature sensor can be added to trigger alerts when a set temperature is reached. Leveraging the power of LoRaWAN® technology, the CT303 ensures stable, long-range wireless data transmission, making it perfect for multi-story commercial and industrial buildings.
