The Littelfuse POWR-Switch provides a simple and economical solution for applications that require selective coordination and shunt trip capabilities. Common applications include elevator circuits, data processing rooms, and building emergency systems.

By utilizing Class J time delay fuses, the POWR-Switch is easily coordinated with other system overcurrent devices. The shunt trip capability allows the POWR-Switch to meet the ANSI/ASME standard that requires power to be automatically disconnected before water is turned on by the fire safety system. The POWR-Switch also features pre-wired control circuits that can help reduce installation costs.

Standard Features:

  • 600 V. 3-pole fuse power switch
  • 200,000 RMS interrupting rating
  • Shunt trip 120 V
  • Control power terminal block
  • Ground lug per NEC
  • Class J fuse block
  • NEMA 1 enclosures

Optional Features:

  • Control power transformer with fuses and blocks.
  • Fire safety interface relay.
  • Key to test switch.
  • Pilot light “on”.
  • Isolated neutral lug.
  • Mechanical interlock auxiliary contact for hydraulic elevators with automatic recall (5 amp 120 VAC rated).
  • Fire alarm voltage monitoring relay.
  • NEMA 3R, 4, and 12 enclosures.

Benefits:

  • Optional features offer flexibility for a variety of applications
  • UL Listed package
  • Lower installation costs than systems with many separate components
  • Pre-wired control circuits lower installation time
  • Lockable Operating handle meets all code and safety requirements
  • No confusion over which building trade is supplying the components
  • POWR-Switch is a single unit…which makes procurement easier than systems with multiple components
