LPS Series POWR-SWITCH STANDARD FEATURES NEW ■ 600V 3-pole fuse power switch ■ 200,000 RMS interrupting rating ■ Shunt trip 120V ■ Control power terminal block ■ Ground lug per NEC ■ Class J fuse block ■ NEMA 1 enclosures OPTIONAL FEATURES 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. 148 ■ Control power transformer with fuses and blocks ■ Fire safety interface relay ■ Key to test switch ■ Pilot light ”On” ■ Isolated neutral lug ■ Mechanical interlock auxilliary 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 LPS Series POWR-SWITCH ORDERING INFORMATION Complete catalog numbers consist of switch catalog numbers and the desired options.
