The Cutler Hammer 1889-1 electrical control relay assembly is an industrial relay block that centralizes control of multiple circuits within automation and machinery. It operates on 110-120V AC, using standard control voltage to actuate its relay contacts. This unit is designed for installation in control panels and other equipment where a dedicated relay assembly is needed to switch signals or power to loads. The 1889-1 model is part of Cutler Hammer's line of industrial control relays, representing a legacy component used in systems built around 110-120V control power.
