mg1 series

isolation switch
mg1 series isolation switch is applicable to distribution network of ac 50hz, rated voltage ac400/690v, rated current 63~3150a, and used for infrequent connection and breaking of circuits and line isolation.

rapid response for safe and stable


● spring-loaded mechanical energy-storage mechanism can be quickly turned on and off, regardless of the operating handle
● materials with high dielectric properties are used to improve performance of protection and operational safety


well-proven, stable and reliable


● dynamic contact dual breakpoint bridge type leaf spring structure, with dynamic and thermal stability, featuring self-cleaning effect
● large isolation distance in the disconnected state, allowing simultaneous triple locking, which is safe and reliable


status display with clear indication


● the front side is equipped with a window for contact on/off status, which provides safety indication
● rear window is available upon request to observe the on-off status of contacts
