Trident®-SR series offers extremely fast operation speeds of just 3.5 cycles for both load and fault interrupting options. Its flexible design can be configured to provide a wide range of solutions for any application, from basic remote operation, to distribution automation, or Smart Grid schemes including Automatic Transfer in under 10 cycles. Trident®-SR switches offer multiple application functionality within a same compact switch footprint.
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 - 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.
Automation - The Trident®-SR switch series was specifically designed to provide the high speed switching required for distribution automation schemes. 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 protection, LaZer custom solutions, or Automatic Transfer in under 10 cycles.
