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 ## Frequently Bought Together - SunLee 3 Pole 40 Amp contactor 120V coil UL DP Contactor HVAC Contactor A2L Compliant 42CF35AF equivalent - SunLee 2 Pole 40 Amp contactor 120v coil UL 2 pole Lighting Load 50 AMP Contactor equivalent to 42CF15AF Condenser Compressor Contactor - SUNLEE 4 Pole 40 Amp 50 RES 120V Coil Contactor fits Siemens 42CF25AF Lighting Heating Refrigeration Contactor, UL Recognized & Approved for UL 60335 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/651630262-sunlee-controls-3-pole-40-amp-contactor-120v-coil-dp](https://www.desertcart.kr/products/651630262-sunlee-controls-3-pole-40-amp-contactor-120v-coil-dp) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-07*
