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.
