Trident®-S is a three phase, spring-assisted load break or fault interrupting switch. Its side-mounted handles can be positioned with a hookstick eye on top or bottom, providing the ideal mechanical advantage for either vertical or horizontal mounting.
Features and Benefits
Construction - Available compact construction with front accessible switch operators and bushings, front and back accessible switch operators and bushings, or front access to operators and rear access to bushings.
Fault Interrupting - Three 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.
Voltage Sensing - Available with fully encapsulated integral voltage sensing for use with voltage indication panel to determine in-phase condition or for use with a relay with up to 1% accuracy.
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.
