Trident®-ST

Trident®-ST is a three phase load break or fault interrupting switch with single phase switched ways. Each phase of the mechanism can be independently opened or tripped and reset, providing the ability to maintain energization of the other phases in the case of a single phase outage or fault. A mechanically ganged reset handle is available.
