As a professional power system supplier in China, Comewill's ZN85 Indoor High Voltage VCB is designed specifically for industrial and power plant applications. It features a modular structure, with the core conductive circuit housed within a sealed insulating cylinder, offering strong protection and a compact size. Its vacuum arc-extinguishing technology is mature and reliable, with a rated voltage of up to 40.5kV and a short-circuit breaking current of up to 31.5kA. It complies with GB1984 and IEC 60947-2 standards and is suitable for frequent operation scenarios.
Rated voltage: 33kV/40.5kV
Short circuit breaking capacity: up to 31.5kA
Operation mode: Manual energy storage operation (energy storage is completed by swinging the handle left and right by 60 °)
Arc extinguishing medium: vacuum (vacuum circuit breaker)
Adopting modular design, the three-phase conductive circuit is placed inside a sealed insulation cylinder, with dust-proof and anti foreign object functions, while reducing the overall size. The operating mechanism is a spring type pneumatic structure, which does not require frequent adjustment.
The ZN85 indoor high voltage VCB is suitable for frequent operation scenarios such as industrial and mining enterprises, power plants, and substations, it can split and combine load current, overload current, and fault current.
As a ZN85 indoor high voltage VCB manufacturer, We, Welcome(Wenzhou) Electric Co., Ltd. ensure compliance with standards of GB1984 and IEC 60947-2, offering robust performance in power plants, substations, and industrial operations. Wholesale ZN85 VCB and ZN85 VCB sample options are available on our platforms.
