CT19BN(W) Spring Operating Mechanism
CT19BN(W) spring operating mechanism is an improvement on CT19 spring operating mechanism, has much better stability and reliability.
CT19BW spring operating mechanism will be used in 35kV (ZW7) outdoor pole mounting vacuum circuit breaker and other vacuum circuit breaker with equivalent closing power,
CT19BN spring operating mechanism will be used in 35kV (ZN23) vacuum circuit breaker and other vacuum circuit breaker with equivalent closing power, its performances can meet
requirements of GB1984 AC High Voltage Circuit Breaker and the product's Technical Conditions; all technical parameters meet or exceed IEC standard.
Two kinds of closing power energy-storages: motor or manual energy-storage; Three kinds of break-brake operations: break-brake electromagnet, over-current trip electromagnet and manual button;
Two kinds of closing operations: closing electromagnet, manual button.
