Traditional leakage circuit breakers only support local manual operation, with high maintenance cost, slow response, no safety interlock, no open protocol, poor anti-interference and no data monitoring. They can hardly meet modern intelligent & safe power distribution needs.
This product directly replaces traditional breakers. With full overload, short-circuit and leakage protection, plus RS485 & Modbus RTU, it realizes remote control, real-time power monitoring and centralized networking. Ideal for industrial, agricultural and residential intelligent upgrading.
