⚡ Product Introduction
Indoor Vcb Circuit Breakers
This series of vacuum circuit breakers is designed for applications that are frequently operated at rated working current or prone to multiple short-circuit breaking currents. The operating mechanism and circuit breaker body are integrated into a design with a reasonable, beautiful and compact layout. The vertical insulating shell can effectively resist impacts under various weather conditions and effectively prevent the vacuum circuit breaker from being damaged by external factors.
