Factory Supply Customized Indoor Vacuum Circuit Breaker, vacuum Switch with CE/IEC

Important FeaturesSpring operation mechanism and circuit breaker are a whole structure with layout arrangement. The compact mechanism connecting indicates reliability. The spring operation mechanism life is over 30000 times to guarantee CB life can be up to 20 000 times.The new compressed spring energy storage mechanism adopts module design. The arrangement of main components is reliable with structure simple and steady performance. The whole mechanism is made of energy storage, opening and closing modules. The performance of closing and opening precedes the national standard and comply with GB1984, IEC56 and DL/403 etc. standard.ZN48A adopts three-dimensional computer design and dynamic simulation optimization design, which make the arrangement of electromagnetic field more reliable and decrease the partial discharge and partial heat.New ideal: visual over travel, the contactor wear and over travel status can be inspected by eyes.Each living parts are packed individually in the sealed insulator, and the insulating performance is reliable.ZN48A has the reliable earthing to ensure the earthing continuously of the circuit breaker from working position to testing position. ZN48A has passed the test of temperature rising of 1.1 times rated current.Technical specificationHVA Series Indoor Vacuum Circuit BreakerNo. Name UnitData1Rated VoltagekV122440.52Rated FrequencyHz5050503Rated CurrentA630/1250/1600/2000/2500/3150/40001250/1600/2000/2500630/1250/1600/2000/25004Rated Short-Circuit Breaking CurrentkA20/25/31.5/40/5020/25/31.520/25/31.55Rated Short-Circuit Making Current (Peak)kA50/63/80/100/12550/63/8050/63/806Rated Peak Withstand CurrentkA50/63/80/100/12550/63/8050/63/807Rated Short-Time Withstand Current (R.M.S.)kA20/25/31.5/40/5020/25/31.520/25/31.58Rated Duration Of Short-CircuitS4449Rated Short-Circuit Current Breaking Times 50302010Rated Single Capacitor Bank Breaking CurrentA630(800)630(800)63011Rated Back-To-Back Capacitor Bank Breaking CurrentA400(630)400(630)(400)12Rated Operating Sequence O-0.3s-CO-180s-COO-0.3s-CO-180s-COO-0.3s-CO-180s-CO13Rated 1 Min Power Frequency Withstand  VoltagekV42659514Rated Lightning Impulse Withstand VoltagekV7512518515Mechanical Life 10000100001000016D.C.
