12kv Indoor Medium Voltage Vacuum Circuit Breaker (ZN63 VS1)

General descriptionGet ready to experience the power of the ZN63(VS1)1-12 indoor M.V.! This indoor switchgear is perfect for industrial and mining enterprises, power plants, substations, and electrical facilities. With a tri-phase AC 50Hz and a rated voltage of 12kV, this switchgear is designed for frequent operation and offers control and protection like no other. The VET operating mechanism and circuit breaker integrated design make this switchgear a fixed installation unit that can also be equipped with special advance mechanisms. The handcart unit used in the composition of this switchgear can use the whole solid seal post with high reliability and is maintenance-free. Plus, it's designed to achieve a smaller circuit breaker, making it even more efficient. For those looking for even more options, the ZN63 can be used with the fixed XGN switchgear or equipped with the KYN2BA 12(GZS) and other handcart switch cabinets. And if you're wondering about the difference between the ZN63 and ZN83 mechanisms, don't worry! All ZN83 mechanisms can be replaced by ZN63 mechanisms, making them universal mechanisms. So, if you're looking for a powerful and reliable indoor vacuum circuit breaker, look no further than the ZN63(VS1)1-12.Main technical parameter ItemUnitDateRated voltagekV12Rated frequencyHz50Rated insulation level1min power frequency withstand voltagepole to earthkV42phasekV48lightning impulse withstand voltagepole to earthkV75phasekV85Power frequency withstand voltage of secondary circuitV2000Rated current(1)A6306306302000125025001600315012501250125025001600315020004000  160031502000400025005000Rated short-circuit breaking currentkA202531.54050Rated short-time withstand currentkA202531.54050Rated short circuit durations4Rated peak withstand currentkA506380100125Rated short-circuit making currentkA506380100125Rated short-circuit current breaking time (class E2)times30Rated single/back to back capacitor bank breaking currentA630/400800/400Clearance between open contactsmm11±1Contact strokemm3~4Allowable wear thickness of contactmm3Average opening speedm/s0.9~1.4Average closing speedm/s0.5~1.0Contact closing bounce timems≤2Different phase of contact closing and openingms≤2Rebound amplitude of opening contactmm≤2Opening time (rated voltage)ms20~50Closing time (rated voltage)ms30~70Mechanical life (M2)times10,000(20,000)Rated operating voltageVAC110/220 DC110/220 Rated operation sequence 0-0.3s-CO-180s-CO (1) It is forced cold air when rated current is 4000AFor more switchgear parts, pls refer to insulation parts: https://china-vacem.en.made-in-china.com/product-group/BbRAnYUjsLrW/Insulation-Accessories-catalog-1.html, or copper tulip contact: https://china-vacem.en.made-in-china.com/product-group/nbUGDIpPuLYM/Tulip-contact-series-1.htmlInternational fairs Company show /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
