Collection Name:  Emergency Lighting Controls Product Line

By Hubbell Control Solutions
Hubbell Control Solutions enclosed bypass Shunt Relays are typically used to bypass a normal control such as a switch, dimmer, or panel mounted relay when used on an emergency circuit. The normally closed relay in the UL924SR1/UL924SR2 connects to the line and load side of the control device. When normal power is lost, the control is bypassed by the normally closed relay and full power is provided to the emergency fixtures.
