CBRM5E	Auto-reclosing low-voltage smart circuit breaker for AC400V 3-phase 4-wire networks. Frame size: 125A/250A/400A/630A, 3P/4P. Integrates power distribution, multi-fault protection, metering & PV grid-tied adaptation.	• 32-bit ARM processor, LCD HMI, online parameter setting • 3-stage overcurrent + over/undervoltage + phase/zero-loss protection; optional terminal overtemp/PV islanding protection • High-precision metering (0.5s class for V/I, class 1 for power), power quality monitoring • Multi-communication (HPLC/Bluetooth/RS485), "4-Remote" control & upgrade • Fault traceability & alarm (trip cause logging, auto-cutoff)	• Strong metering & communication: industry-leading metering accuracy, multi-protocol support, smart remote control • Stable & durable: high breaking/withstand capacity, long mechanical/electrical life • Fast response: auto-reclosing within 5s after voltage recovery • Ultra compact in size with high integration

Operating EnvironmentThe installation site shall be free from conductive dust, corrosive gases, flammable or explosive gases, and rain or snow ingress.
Altitude: Not exceeding 2000m.
Ambient Temperature: -5°C to +40°C, with a maximum daily average temperature ≤ +35°C. Relative Humidity: ≤ 50% (when the ambient temperature is +40°C). The external magnetic field at the installation site shall not exceed five times that of the earth's magnetic field in any direction.
The installation location shall have good ventilation and heat dissipation conditions.
When HPLC (High-speed Power Line Carrier) communication is required, it must be ensured that all communication devices operate under the same transformerApplicationThe Smart IoT Circuit Breaker has a rated insulation voltage of 1000V and is suitable for three-phase four-wire distribution networks with AC 50Hz, a rated voltage of 400V, and a rated current up to 630A. It provides indirect contact protection; prevents fire hazards caused by earth fault currents resulting from equipment insulation damage, and is used for distributing electrical energy and protecting lines against overload and short circuit. It also offers protection against over-voltage, under-voltage, and phase loss.
This product complies with the following standards:
IEC60947-1 Low-voltage switchgear and controlgear - Part 1: General rules
IEC60947-2 Low-voltage switchgear and controlgear - Part 2: Circuit-breakers
