The economically priced relays are available prepackaged in their own Nema 1 enclosure or in panel versions to be installed inside an existing enclosure. Emergency lighting relays can be ordered with a standard two-position on/auto override switch.The override switch models can be used for testing purposes to verify your emergency load is being switched properly.
