Product Introduction
VXB-40.5(P) Series Indoor AC High-Voltage Vacuum Circuit Breaker
Product Overview：
The VXB-40.5(P) Series Indoor AC High-Voltage Vacuum Circuit Breaker is a new generation of draw-out vacuum circuit breakers developed by our company to meet the demands of the domestic power market. It is suitable for indoor high-voltage distribution equipment with three-phase AC 50Hz and a rated voltage of 40.5kV. It can be used for receiving, controlling, distributing, and protecting electrical energy in industrial and mining enterprises, power plants, and substations.
The product complies with relevant national standards such as GB and DL, as well as international standards like IEC, achieving performance levels equivalent to M2-E2-C2.
Product Features：
▲Complies with GB/T1984-2014 and DL/T403-2017 standards.
▲The circuit breaker features a rational, aesthetically pleasing, and streamlined overall layout.
Primary conductive circuits can utilize solid-sealed busbars or standard insulating tubes to accommodate diverse customer requirements.
▲Features a modular spring mechanism with superior performance and enhanced mechanical stability, suitable for high-frequency operation. Meets M2-class requirements with a mechanical life of up to 20,000 operations.
▲Rated current up to 4000A, rated short-circuit breaking capacity up to 40kA.
▲Flexible cabinet configuration options include circuit breakers with pole spacings of 300mm/440mm, compatible with 1400mm/1680mm wide KYN61 switchgear. Custom non-standard products can also be manufactured according to user requirements.
