Scope of application
The GMLE series plastic shell circuit breaker is suitable for circuits with AC 50Hz, rated insulation voltage AC690V, and rated current up to 630A and below, providing indirect contact protection for people, i.e. the danger of increased ground voltage due to equipment insulation damage. Provide protection against potential fire and other hazards caused by long-term grounding faults that cannot be detected by overcurrent protection devices. Provide short circuit and overload protection for equipment, and can be used for infrequent switching of circuits and infrequent starting of motors.
