GDM1LE series residual current circuit breaker is suitable for leakage protection in AC power supply system with AC neutral frequency of 50Hz or 60Hz and rated working voltage up to 400V. It can also be used to prevent electrical fire hazards caused by ground fault currents due to equipment insulation damage. It can also be used to distribute electrical energy and protect lines and power equipment from overload, short circuit, and other faults. At the same time, it can also be used as infrequent start-up, overload and short-circuit protection of the motor. The circuit breaker has the characteristics of small volume, high breaking capacity, short arcing and residual operating current, adjustable operating time, etc., and can be equipped with alarm contacts and other auxiliary accessories.
