indoor permanent magnet vacuum circuit breaker
?ZN63 (VS1)-12 Series Vacuum Circuit Breaker,Website:http://www.qdyonghuaxu.com, adopts solid insulation structure, use of advanced solid epoxy sealing technology, the first time, the vacuum interrupter. A leading electrical circuit, insulation and other support to become an integrated combination of solid seal pole. Successfully from a fundamental solution of the vacuum breaker gas environment, tolerance issues, make it broader. Integrated solid-pole closure of the fluent use of a self-ventilation technology cleverly solved the structure of solid insulation caused by heat dissipation.NOItemUnitsparameters1Rated voltageKV122Rated insulation levelRated Lightning Impulse voltage toleranceKV751min Frequency voltage423Rated short-circuit breaking currentKA20/2531.5404Rated currentA630 1250630 1250 1600 2000 2500 31501250 1600 2000 2500 3150 40005Rated thermal stability of current (RMS)KA20/2531.5406Dynamic Stability rated current (peak)63801007Rated short-circuit closing current (peak)63801008Rated short-circuit breaking current breaking numbertimes509Frequency tolerance of the secondary circuit voltage (1min)V200010Rated operating sequence0-0.3s-CO-180s-CO0-180s-CO-180s-CO(40kA)11Rated thermal stabilization timeS412Rated a single / back-to-back electric current breaking device group630/400 800/400(40KA)13Mechanical lifeTimes10000
