Modular Frame Circuit Breaker with Communication

The Modular Frame Circuit Breaker with Communication from Zhejiang Chenhai Electric combines high performance with digital connectivity. Its modular design allows interchangeable trip units, auxiliary contacts, and voltage coils. The breaker is available in three frame sizes covering 630A to 6300A. The built‑in communication port supports Modbus‑RTU, allowing integration with Industrial Energy Management systems. For complete distribution solutions, use it alongside High‑Quality Energy Meters and Reliable Energy Meters to monitor consumption at the supply point. The breaker’s electronic trip unit provides selective coordination with downstream Circuit Breakers, minimizing outage zones. For generator protection, it includes reverse power and underfrequency detection. The drawout mechanism features a safe operation interlock that prevents the breaker from being closed unless fully inserted. The shutter system covers primary contacts when the breaker is withdrawn, protecting maintenance p…
