POWR-Switch is a single unit...which makes procurement
easier than systems with multiple components
The Littelfuse POWR-Switch provides a simple and econom-
ical solution for applications that require selective coordina-
tion and shunt trip capabilities. Common applications include
elevator circuits, data processing rooms, and building emer-
gency 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 automat-
ically disconnected before water is turned on by the fire safe-
ty system. The POWR-Switch also features pre-wired control
circuits that can help reduce installation costs.
