How do I know if this is the right contactor for my equipment?

If your old contactor has a 120V Coil and is rated 40A, 30A, or 25A. This 40A model is a heavy-duty upgrade for lower amp units. Rule: Coil voltage must be exact; Amps can be higher, but never lower than your original one.

Can I use this to control 277V or 480V lighting circuits

Yes. It's perfect for lighting control. The "120V Coil" means you can use a standard 120V wall switch, timer, or photocell to control lighting circuits (up to 600V, including 277V/480V). It works for LED, ballast, and incandescent lighting loads.

Does this contactor support Auxiliary Contacts?

Yes. This model features standard mounting points on the side for adding auxiliary contact blocks (Snap-on type), check our SUNLEE Auxiliary switch.

Can I use this to build a remote starter for my dust collector or shop compressor?

Yes. It allows you to control high-power 240V or 3-Phase motors using a standard 120V switch or wireless remote. Simply route motor power through the poles and connect your 120V trigger to the coil terminals.

My old contactor buzzes/hums — will replacing it fix that?

Often yes. Buzzing can be caused by a worn coil/armature, pitted contacts, or low control voltage. Replacing the contactor commonly resolves noise if the control voltage is stable and wiring is correct
