Leakage Circuit Breaker250A 3p/4p Residual Earth Leakage Protection Function CE MCCB Manufacturer′ S Case Earth

HMKM1L series plastic case circuit breaker with residual current protection is one of the new circuit breakers designed, manufactured, developed and developed by the company using advanced CAD/CAM/CAE technology.

The rated insulation voltage is 800V, which is suitable for infrequent switching in the circuit with AC 50Hz, rated working voltage of AC400V and rated current of 800A and infrequent motor starting

Use. The circuit breaker has overload, short circuit and undervoltage protection functions, which can protect lines and power supply equipment from damage. At the same time, it can provide indirect contact protection for people and overcurrent protection

The undetectable long-term grounding fault may cause fire hazard and provide protection. When other protective devices fail, the circuit breaker with rated residual action current of 30mA can directly

Contact provides additional protection.

The circuit breaker has the characteristics of small volume, high breaking height, short flashover, anti vibration, etc.

The circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally).

The circuit breaker shall not reverse the incoming line, that is, only 1, 3 and 5 are allowed to be connected to the power line, and 2, 4 and 6 are allowed to be connected to the load line.

Circuit breaker products shall meet the following standards:

IEC60947-1 and GB14048.1-2006 General

IEC60947-2 and GB14048.2-2008 Circuit Breakers and Appendix B Circuit Breakers with Residual Current Protection

The circuit breaker is suitable for isolation, and the symbol is "".

The ambient medium temperature shall not be higher than+40 ºC and not lower than - 5 ºC; And the 24-hour average value shall not exceed 3
