L7 Residual current circuit breaker 2 Pole
APPLICATION
The RCD is in conformity with the standards of IEC1008,GB16916 and BS EN61008.The RCD can cut off the fault circuit immediately and on the occasion of shock hazard or earth leakage of trunk,thus it is suitable to avoid the shock hazard and fire caused by eartg leakage.
The 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 phases 400V 50 to 60HZ,RCD is not suitable for using on DC pulse system.
