Zn63 (VS1) -12 Side Mounted Vacuum Circuit Breaker

ZN63 (VS1) type indoor high voltage vacuum circuit breakerProduct overviewVS1 (ZN63A) type indoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is the indoor switchgear used for 12kV power system, power grid equipment as well as protection and control unit of the power equipment in industrial and mining enterprises. Due to its special merits, vacuum circuit breaker is in particular suitable for frequent operation at rated working current or for multiple times of short circuit current breaking. It is of operating mechanism and circuit breaker integrated design. It can serve as the fixed installation unit or be equipped with the special feed mechanism to form the withdrawable unit.Service conditiona) Ambient temperature: maximum +40ºC; minimum -15ºCb) Ambient humidity: Daily average RH ≤95%            Monthly average RH ≤90%Daily average steam pressure ≤2.2×10-3MPa:Monthly average steam pressure ≤1.8×10-3MPac) Altitude:               ≤2000md) Seismic intensity: no more than 8e) In places without water dripping, inflammable and explosive hazards, chemical corrosive gases or violent vibration.Technical specificationNo.ItemsUnitParameters1Rated voltagekV122(1min)Rated short duration power frequency withstand voltage (1min)423Rated lightning impulse withstand voltage(peak)754Rated frequencyHz505Rated currentA6301250125016002000 2500 31501250 16002000 2500 31506Rated short circuit breaking currentkA2531.5407Rated short-time withstand current 2531.5408Rated short-circuit durations49Rated peak withstand currentkA638010010Rated short circuit closing current 638010011[1min]Secondary circuit power frequency withstand voltage (1min)V200012Rated single/back to back capacitor bank breaking currentA630/400 (800/400 for 40kA) 13Rated capacitor bank inrush making currentkA12.5 (frequency of no more than 1000Hz)About Our CompanyShandong Witry Electric Co., Ltd. is a professional electrical equipment enterprise located in Shandong province east of China, integrating R&D, design, manufacture, supply and export.The main products are high-voltage transmission and transformation equipment, high and low-voltage switchgear, cable tray. the products are widely used in power, metallurgy, chemical industry, machinery, medicine, mining, textile and other industries.   Mission & Vision Thinking and doing more,  make customers do less.Being more efficient,  make customers more beneficial.Represent with quality,  make reputation with service.Sincerely treat guests,  make friends in business.We are committed to producing only the highest quality products that meet or exceed our customers' expectations and requirements.
