1 Applications:
The RCCB NOL1 are mainly used in varieties of factories; enterprises and building construction, 1 phase 230V and 3 phase 400V 50/60Hz, rated Current(A): 16, 20, 25, 40, 50, 63. They are not suitable for use in DC pulse system. They 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. They are in conformity with the standard of IEC61008.
