ZN85-40.5 Indoor Handcart Vacuum Circuit Breaker with 300MM Phase Distance

Model: ZN85-40.5

Description:

ZN85-40.5/T(3AV3)indoor handcart vacuum circuit breaker is suitable for three-phase,AC50Hz with 40.5KV ratedvoltage.It can be used for industrial and mining enterprises,power plants and substations as load current andoverload current fault current,and is suitable for the occasion with frequent operation. The circuit breaker adopts an upper and lower arrangement structure to effectively reduce the depth of thecircuit breaker.It adopts the composite insulation structure,the three-phase arc extinguishing chamber and theassociated electrified body.Separated by three independent epoxy insulation cases,the circuit breaker meets theair distance and creepage requirements under normal operating conditions after the composite insulation structureand it effectively reduces the size of the circuit breaker.The main conductive circuit vacuum interrupter and thedynamic and static conductive connection are installed in the insulation tube,so that the phase to phase distance isonly 300mm.The main circuit electrical connections are all fixed connections with high reliability.
