New generation of fully insulated VCB originated from Germany's mature technology featuring national patents

MV intelligent vacuum circuit breaker

Based on Germany’s advanced medium voltage circuit breaker manufacturing technologies and through independent innovation,MINGHAN have developed the new generation of 10 KV-35KV intelligent circuit breakers (V-Sa series) which have obtained many patents.

Features

Complete modularized and standardized operating mechanism, Stable and reliable ,Convenient for maintenanceFully insulated pole with high protection level and ability of anti-corrosionTulip contacts of pressure spring style, Reliable connection, Low fault rate.Intelligent control and diagnosisElectronic current/voltage sensorMechanism position sensorReal-time temperature measurement of dynamic contact

Field of Application

V-Sa indoor vacuum circuit breakers are widely used in power plants, power grids, petrochemical industry,metallurgy,mining,urban infrastructure and civil works such as airports,subways,ports and residential quarters for the control and protection of cables, overhead lines,transformers,motors,generators and capacitor banks.
