Trident®-SP is a single phase, spring-assisted load break or fault interrupting switch. It provides fault protection through vacuum interrupters with integral current transformers and overcurrent control options. Both vertical or horizontal mounting options are available.
Features and Benefits
Construction - Available compact construction with front accessible switch operators and bushings, or front access to operators and rear access to bushings.
Fault Interrupting - Single phase fault interrupting up to 12.5kA.
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.
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.
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 installated switchgear. Programming for automatic source transfer, protection, or LaZer custom solutions are available.
