Audited Supplier ZN85-40.5/T2000-31.5 type indoor high voltage vaccum circuit breaker,suitable for three-phase AC 50Hz,rated voltage 40.5kV power system,for industrial and mining enterprises,power plants and substations as the division of load current ,overload current ,fault current.The circuit breaker adopts the upper and lower arrangement structure with the operating mechanism,effectively reducing the depth of the circuit breaker .
The spring operating mechanism specially designed for this new type of circuit breaker is installed in the circuit breaker frame,and its structural characteristics are more suitable for the upper and lower layout of the circuit breaker ,and become an intergral part of the overall structure of the circuit breaker .The design of the mechanism is simple ,and the output curve and its performance are more suitable for 40.5kV vaccum circuit breaker characteristics and requirements.
The circuit breaker is suitable for frequency operation and a variety of occasions and places with harsh operating conditons.
