When the dc coil energizes, the core generates a steady magnetic field that holds the armature closed. Ac relays: In theory, ac can be used to operate a dc relay. But ac drops to zero every half ...

Coils are available in voltages up to 600 V, commonly in 110, 220, 240, 380, 440, 480, and 500 V for 25, 50, and 60 Hz. A dc contactor operates like an ac contactor.
