BKV3(VS1)-12KV vacuum circuit breaker

BKV3-12KV vacuum circuit breaker

BKV3(VS1)-12KV vacuum circuit breaker in terms of mechanisms,VS1-Series vacuum circuit breakers are given special optimization to transmission parts. Modular spring mechanisms have such advantages as convenient maintenance, short power-off maintenance, high versatility of parts, and boast better compatibility with vacuum interrupters which greatly improves the technical parameters.

BKZC(R)-12 Medium Voltage Drawout type vacuum contactor 400A 630A

BKZC(R)-12 Drawout type vacuum contactor

BKZC(R)-12 Medium Voltage Drawout type vacuum contactor 400A 630A vacuum AC contactors utilize vacuum bottle encapsulated contacts to suppress the arc. This arc suppression allows the contacts to be much smaller and use less space than air break contacts at higher currents. As the contacts are encapsulated, vacuum contactors are used fairly extensively in dirty applications, such as mining.

ZN12-40.5 indoor medium voltage vacuum circuit breaker

ZN12-40.5 indoor vacuum circuit breaker

ZN12-40.5 indoor medium voltage vacuum circuit breaker the circuit breaker for the ceramic structure, using the longitudinal magnetic field contacts, is small, the proliferation of breaking arc generated when current distribution in the contact on the same local melting phenomenon does not occur, but also has a low arc energy voltage (20-200V) and low chopping current (4-5A).

ZN-85-40.5 (modular type) indoor vacuum circuit breaker

ZN-85-40.5 indoor vacuum circuit breaker
