Series 781 SPDT Ice Cube Relays

15 Amp, SPDT Operation

The Series 781 Electromechanical Ice Cube Relay is a full-featured SPDT relay that can be used to handle loads up to 15 amps for AC or DC circuits. It features a flag 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. For testing the operation, a removable lock-down lever holds the test button in place. The clear plastic housing gives a view of the contacts, and there is a removable I.D. tag for labeling the circuit.
