NDM2L series molded case leakage circuit breakerthe rated insulation voltage of1000Vfor AC 50Hz or 60Hzrated working voltage 380V/400V/415Vdo not frequentconversion and the motor is not frequent use.Circuit breakers with overloadshort circuitand undervoltage protectionto protect the line and power equipment from damage.AC-type leakage circuit breakersto ensure that they are tripped with the remainingsinusoidal alternating current of the DC component without any sudden or slow rise.Type A leakage circuit breakers are guaranteed to be tripped with respect to the residualsinusoidal current and the residual pulsating direct current(with or without specifiedsuperposed DC component)that is suddenly applied or slowly raised.
