The Series 781 & 782 Ice Cube Relays are full-featured relays that can be used to
handle loads up to 15 amps for AC or DC circuits. It features a ag status indicator
and a LED status lamp to let the user know when the relay is activated. In order to
differentiate between AC and DC actuated models, the push-to-test button is color
coded and a removable lock-down lever holds the test button in place.
