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.
