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: My compressor is 480V 3-Phase. Will this 24V coil contactor work?** A: Yes. The "24V" refers to the thermostat signal (Coil), not the main power, 240V is for the motor. This contactor is rated up to 600V, so it easily handles your 480V unit. **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 contactor to control a bank of LED or ballast lights in a warehouse?** A: Yes, absolutely. You can use it to switch three separate 120V or 277V lighting circuits simultaneously using a single 24V low-voltage signal from a timer or photosensor. **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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by F***R on April 11, 2026* ### ⭐⭐⭐⭐⭐ Review *by B***L on March 30, 2026* ### ⭐⭐⭐⭐⭐ Review *by T***. on February 16, 2026* ## Frequently Bought Together - SUNLEE UL 3 pole 40 Amp Contactor 24v coil A2L Compliant fits 42CF35AJ equivalent Definite Purpose Contactor - BOJACK 2 Poles FLA 40 Amp Coil 24 VAC Air Conditioner Condenser Compressor Contactor AC Definite Purpose Contactor - 24V 40VA Control Transformer， Primary 120, 208, 240V Secondary 24V Isolation Transformers，24V Transformer with Foot Mount for HVAC Furnace Multi Tap --- ## 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.it/products/243998305-sunlee-ul-3-pole-40-amp-contactor-24v-coil-a2l](https://www.desertcart.it/products/243998305-sunlee-ul-3-pole-40-amp-contactor-24v-coil-a2l) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-07*
