China N7Ln factory and manufacturers

N7Ln

The new design RCD is in conformity with the standards of IEC1008, GB1691 and BS EN61008.

The RCD 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.This RCD

is mainly suitable for using in variety of plants and enterprises, building construction, commerce,

guesthouses and families. It can be used in circuits up to single phase 230V, three phase 400V 50

to 60Hz, RCD is not suitable for using on DC pulse system.
