RIB Functional Devices Enclosed Lighting Relay - UL924 - 20 Amp - SPDT - 24VAC/DC Coil

The UL924 emergency lighting relays from Functional Devices are used for automatic load control or bypass/shunt applications to turn on emergency lighting in the event of power loss. When normal power is present in automatic load control applications the relay coils are activated, allowing for the emergency panel to be fed from normal power and the load can be switched on or off using individual wall switches. When normal power is lost, the relay coils are deactivated and the contacts are closed, allowing for automatic transfer switch to change over to backup generator power and the lighting load is illuminated, regardless of the wall switch position or controller setup.

The ESR2401B is a UL924 listed 20 amp (SPDT) enclosed lighting relay with 24VAC/DC coil

Made in U.S.A.
