Product Details

Summarize

TN1M3LE series residual current circuit breakers (hereinafter referred to as circuit breakers), mainly applicable to AC 50Hz, rated voltage 400V, rated current to 800A power distribution network, used to provide indirect contact protection of electrical equipment, can also be used to prevent damage to the insulation of the equipment, the generation of ground fault current caused by the risk of fire, and can be used to distribute power and protect the line and power equipment of overload and short circuit. It can also be used to distribute electric energy and protect the line and power equipment from overload and short circuit, and can also be used for infrequent conversion of line and infrequent starting of motor. Conventional leakage protection module with residual current protection circuit breaker samples the working power as two-phase. This series of circuit breaker is three-phase, if any one phase is missing, the leakage protection module of the circuit breaker can still work normally; the rated residual action current 1△n and the upper limit of disconnecting time can be adjusted according to the actual situation on the spot; when the phase voltage is lowered to 50V, the leakage protection module can still work normally with the function of leakage alarm output.

Products comply with: IEC60947-2, GBI4048.2 standard.
