MSL7 Residual Current Circuit BreakerCurrent

  • MSL7 residual current device is in conformity with the standards of IEC61008. It can cut off the fault circuit immediately on the occasion of shock hazard or earth leakage of trunk line. Thus it is suitable to avoid the shock hazard and fire caused by earth leakage. It can be used in circuits up to single phase 240V, threephase 415V, 50 or 60Hz.
