CF7 Residual Current Device (RCD)

CF7 Residual Current Device Introduction:

The Residual Current Device (RCD) is in conformity with the standards of IEC1008,GB16916 and BS EN61008. The RCD can cut off the fault circuit 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 of plants and enterprises, building construction, commerce, guesthouses and families. It can be used in circuits up to single phase 230V, three phases400V 50 to 60Hz,RCD is not suitable for using on DC pulse system.
