## Questions & Answers

**Q: How do I know if this is the right contactor for my equipment?**
A: 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.

**Q: Can I use this to control 277V or 480V lighting circuits**
A: 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.

**Q: Does this contactor support Auxiliary Contacts?**
A: Yes. This model features standard mounting points on the side for adding auxiliary contact blocks (Snap-on type), check our SUNLEE Auxiliary switch.

**Q: Can I use this to build a remote starter for my dust collector or shop compressor?**
A: 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.

**Q: My old contactor buzzes/hums — will replacing it fix that?**
A: 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

### ⭐⭐⭐⭐⭐ Good value
*by M***C on February 11, 2024*

I bought this part to replace a 30 year old contactor that was controlling three banks of baseboard heaters in my home. The old ITE contactor was an extremely solid and heavy component and the Sunlee contactor was much lighter and smaller than the ITE component. The Sunlee current ratings were actually more than double what I required and overall worked perfectly for my application. The noise from the contactor is less than for my old contactor and the coil current is lower. The coil connection is not marked, but is obvious. One warning, the bottom mounting plate of the contactor actually holds in the spring for the contacts, so I recommend not removing it.
