The ABB ZA110-4 is a contactor and starter coil, sitting under the broader Contactors and Starters category within Circuit Breakers, Fuses & Protection. It's the energizing element that pulls in the contactor armature — the part that makes or breaks the power circuit when the control signal arrives. No need to gut the whole line if this coil fails; it's a component-level swap, not a full contactor replacement.
