Product Description

APPLICATION                                                                                                                              

   CKYL1-63 RCCB is in conformity with the standard of IEC61008. The RCCB can cut off the

fault circuit immediately on the occasion of shock hazard or earth leakage of trunk, thus, it is

suitable to avoid the shock hazard and fire caused by earth leakage.
   The RCCB is mainly suitable for use in varieties of plants and enterprises, building

construction 1 phase 230V and 3 phase 400V 50/60Hz. RCCB is not suitable for use in DC

pulse system.
