Product Description

Indoor High Voltage Solid Vacuum Circuit Breaker Embedded Pole Vcb with Handcart ZN63A-24

ZN63A (VS1) -24 indoor AC high voltage vacuum circuit breaker is the latest generation 24kV vacuumcircuit breaker developed by our company refer to domestic and foreign technology. The main design concept isuse solid sealed insulation for the main conductive circuit to improve design operating mechanism, makes theinsulation performance of the circuit breaker stable, the mechanical reliability and the breaking perfomancegreatly improved, and truly achieves maintenance-free,longer mechanical and electrical life. And there is noexplosion danger and pollution. lt is used for the protection and control of single busbar system electrical facilitiesfor industrial and mining enterprises, power plants and substations. lt is suitable for places with frequenoperations and can also be used for special occasions such as capacitor banks. This product complies withnational standards GB1984-2003 "AC High Voltage Circuit Breaker" and lE62271-100 "AC Hiah Voltage CircuiBreaker" standards. Meet DL /T403 "Ordering Technical Conditions for 10-35kV Indoor High Voltage VacuumCircuit Breakers.
