Product Description

VSG/C-24 series lateral type indoor high voltage vacuum circuit breaker applies to three-phase AC 50(60)Hz 24KV power system, which could be used for switching load current, overload current and fault current in industrial and mining enterprises, power plant, transformer substation and suitable for frequently operated occasions. It also widely applies to projects, as power plant, power

system, petrifaction, metallurgy, metro, airdrome, building, etc.

Features
1. Made of new material with high strength, high conductivity and high elasticity
2. Epoxy resin integrated molding, insulation tube with additional inner skirt and reinforcement, improve the level of insulation and resistance to dynamic and stable current
3. Arc extinguishing vacuum tube, anti-corrosion and wear-resisting, long contact life, more times allowed to open and close
