Match SC-E04 or SC-E04H5-C on the original contactor label.
Match AC 110V 50Hz coil requirement and the A1/A2 coil terminal location.
Match 3-pole terminal layout, screw-terminal style, current/load rating and mounting position.
Check the equipment wiring diagram before energizing the circuit.
Disconnect and lock out power before replacing a contactor.
Label each wire before removal and reinstall wires to the same terminal positions.
Inspect the panel terminals for heat damage, corrosion or loose hardware.
Installation should be performed by a qualified person familiar with electrical control panels.
Q: Is this for every 110V contactor? A: No. It is for SC-E04 / SC-E04H5-C style applications with matching voltage, terminals, ratings and mounting.
Q: Can it replace a different coil voltage? A: No. Do not use it in 24V, 220V, 230V or other non-matching coil-voltage panels unless the original contactor and diagram confirm compatibility.
Q: What symptoms can a contactor replacement help with? A: It may help when diagnosis confirms a failed, burned, sticking or damaged contactor.
