main features
According to the pole number, it is divided into 2 levels, 3 poles and 4 poles.
It can be divided into two parts: distribution and motor protection.
According to the residual current breaking time, it is divided into two types: non delay type and delayed type.
According to the operation mode, the handle is directly operated, the handle is rotated and the motor is operated;

The rated insulation voltage of SRM1E series residual current operated circuit breakers is 690V. It is mainly used in the circuit of 50 Hz AC, 400 V rated voltage, 800A rated current for non-frequent conversion and motor starting. The circuit breakers have the functions of overload, short circuit and under-voltage protection, and can protect the lines and power supply equipment from damage. At the same time, it can also provide protection against long-standing grounding faults which can not be detected by overcurrent protection. Conventional circuit breaker leakage protection module with residual current protection has two-phase working power supply sampling. This series of plastic case circuit breakers are three-phase, any phase is missing, and the circuit breaker leakage protection module can still work. Normal operation; rated residual action current L Delta n adjustable; residual current action time adjustable, with leakage alarm output function.
The circuit breaker implements the following criteria:
General principles of IEC60947-1 and GB14048.1 2000;
IEC 60947-2 and GB14048.2 "2000" Low Voltage Circuit Breakers and Appendix F with Electronic Overcurrent Protection Circuit Breakers Additional Requirements;
IEC60947-4 and GB14048.4 contactor and motor starter;
IEC60947-5.1 and GB14048.5 electromechanical control circuit electrical apparatus.
