Features and Benefits

  • Construction – Available compact construction with front accessible switch operators and bushings, or front access to operators and rear access to bushings.

  • SafeVu Visible Break – Available with an innovative visible break built into the switch, which eliminates the need to remove elbows or use externally mounted components to provide a visible open.

  • Automation – Available for motor automation with mounted or portable control. A variety of relays such as SEL, ABB, and GE are available with G&W Electric programming and cabinet construction. Cabinets can be ordered in a low voltage enclosure for padmount, and pedestal, wall mount or IP68 rated submersible for vault installed switchgear. Programming for automatic source transfer, protection, or LaZer custom solutions are available.

  • Fault Interrupting – Single phase fault interrupting up to 12.5kA.

  • Self Powered Protection – G&W Electric Type VI controls are self-powered by the fully encapsulated current sensors in the Trident. Standard industry curves including fuse emulation curves for overcurrent and ground fault protection.
