Dwyer Instruments: Series 783, 3PDT Ice Cube Relays

15 Amp, 3PDT Operation

The Series 783 Electromechanical Ice Cube Relay is a full-featured 3PDT relay that can control up to 3 devices with a single trigger. 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 lockdown 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. The Series 783 can handle loads up to 15 amps.
