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.
ꢀ
NEMA 3R, 4, and 12 enclosures
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.
BENEFITS
ꢀ
Optional features offer flexibility for a variety of applica-
tions
ꢀ
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
