DSY-VBI-12/24 indoor high-voltage vacuum circuit breaker
DSY-VB1-12/24 indoor high-voltage vacuum circuit breaker is a modular side-mounted structure, with the operating mechanism and the primary part arranged front and back, and the primary part is a three-phase floor-standing structure. The upper and lower outlet seats and the arc extinguishing chamber are sealed into one piece using the epoxy resin APG process, so that there is no dust accumulation on the surface of the arc extinguishing chamber, which can prevent the vacuum arc extinguishing chamber from being damaged by external factors and ensure that it can be used in a humid, hot and dirty environment.
