AL33 Residual Current Device Introduction:

The Residual Current Device (RCD) is in conformity with thestandards of IEC1008, GB16916 and BS EN61008. The RCD can cut off the faultcircuit immediately on the occasion of shock hazard or earth leak of trunk,thus it is suitable to avoid the shock hazard and fire caused by earth leak.
The Residual Current Device (RCD) is mainly suitable for using in variety ofplants and enterprises, building construction, commerce, guesthouses andfamilies. It can be used in circuits up to single phase 230V, three phases400V50 to 60Hz,RCD is not suitable for using on DC pulsesystem.
