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.

LPS200P70 General Description
The LPS200P70 is a packaged Aluminum Gallium Arsenide / Indium Gallium Arsenide(AlGaAs/InGaAs) Pseudomorphic High Electron Mobility Transistor (PHEMT), utilizing anElectron-Beam direct-write 0.25 mm by 200 mm Schottky barrier gate. The recessed "mushroom"Ti/Pt/Au gate structure minimizes parasitic gate-source and gate resistances. The epitaxial structureand processing have been optimized for high dynamic range. The LPS200's active areas arepassivated with Si3N4, and the P70 ceramic package is ideal for low-cost, high-performanceapplications that require a surface-mount package.
