General
YCM7, YCM7RT, YCM7T/A, YCM7RE series circuit breaker is a new generation of breaker. This breaker is applied for the distribution network of AC 50Hz, rated insulation voltage 800V, rated working current up to 800A, which is for electric energy distribution, circuit protection, protection power supply facility from destroying by the fault of overloading, short circuit and undervoltage, meanwhile it is also used for protection from unfrequent starting, over loading, short circuit and undervoltage of the motor.
General
1.Protection against the effects of sinusoidal alternating earth fault currents
2.Protection against indirect contacts and additional protection against direct contacts
3.Protection against fire hazard caused byinsulation faults
4.Controlling and Switching
5.Used in residential building,non-residential building,energysources,industryand infrastructure
