Product Application

Main feature

♦Residual current three-phase protection: SLM1L circuit breaker realizes ground fault protection. The conventional leakage protection module with residual current protection circuit breaker samples the working power supply as two-phase. This series of circuit breakers is three-phase. If any phase is missing, the circuit breaker leaks. The protection module is still working properly

♦Field adjustable: rated residual operating current IΔn and residual current operating time (non-delay and delay) can be adjusted according to the actual situation

♦Low voltage protection: When the phase voltage is reduced by 50V, the leakage protection template can still work normally

♦With leakage alarm output function: When the residual current of the equipment or line reaches or exceeds the set value, the circuit breaker with the leakage alarm unit module outputs a passive contact signal to drive the corresponding alarm device.

♦The installation is interchangeable: the dimensions and mounting dimensions are the same as those of the SLM1 series circuit breakers, and the installation has good interchangeability.
