Product feature

DZ108(3VE) circuit mould case breakers adopting the advanced technology orlow voltage circuit breaker from germany,the circuit breaker meets the germany stancard, it is the replacing product of the DZ5-20,DZ5-50,DZ15-60 circuit breaker in the country.
Applying to the circuit of AC voltage up to 660V, frequency of 40-60Hz, and rated current of 0.1-63A the circuit breaker does the make and break operation to the motor, distribution wire or other electrical device in the underload of Ac3.with the protection of overload and short circuit
Note: Ac3-the start , operation and break of squirre-cage async-honous generator.
