DZS8-12{RV1011)

nnnn

DZS8-25(3RV1021)

nnnn

Application

nnnn

DZSS(3RV)seried circuit breakers are mainly used for the overload,short-circuit and phase-failure

nnnn

protection for motors in the circuit of AC 50/60Hz,rated operating voltage up to 660v,rated

nnnn

operating current from 0.11A to ZSA.They can be also used for circuit protection in the circuit of

nnnn

0.11A-25A.
