TESL4 RCCB
TESL4 RCCB



1.Application

TESL4 residual current breaker is used in circuits up to single phase 230V, three phase 400V 50/60 Hz.RCCB is not suitable for use on DC pulse system. The RCCB can cut off the fault circuit immediately on theoccasion of shock hazard or earth leakage of trunk Thus it is suitable to avoid the shock hazard and firecaused by earth leakage. The RCCB is mainly suitable for use in variety of plants and enterprises,buildingconstruction, commerce, guesthouses and families. It conforms with the standards of IEC61008.
