I haven’t felt the temperature, but I don’t think that would be a problem. Usually it is the switching that limits the life on these parts. **Q: Will this support 10 AWG?** A: I believe #10 will fit, but don’t over tighten the screw, as it may break the frame. I used #12 jumper, then spliced it to the larger wire. **Q: Do you have a test report and certificate of conformity for this product?** A: no **Q: what is the current drawn by the 110V AC coil when energized?** A: It is .3 amp @ 120 volt coil. Point three amp at 120 volt coil. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as expected *by J***S on May 6, 2026* Great buy ### ⭐⭐⭐⭐⭐ Well Made *by J***B on March 21, 2026* Great contractor. It is well made and it works. ### ⭐⭐⭐⭐⭐ Alexa, Turn On My Heater at 2 am, Off at 6 am. *by R***O on April 25, 2026* My garage heater is 220 volts but Alexa/Tuya power switches are only 110. I solved the problem by installing this contactor inside the heater cabinet. Now the 110 volt Alexa/Tuya device sends power to the contactor which switches the 220 heater on or off. ## Frequently Bought Together - Baomain HC1-25/20 Universal AC Contactor AC 110V-120V 25A 2 Pole 2NO Circuit Control 35mm DIN Rail - VAMRONE 10 Piece Aluminum DIN Rails, 12 Inches Long, 35mm Wide, 7.5mm High, Top Hat Slotted DIN Rail with RoHS, Extra Premium Screws Included for Hardware Components Mounting - Chtaixi AC Miniature Circuit Breaker, 20 Amp 120V/240V 1 Pole DIN Rail Mount Circuit Breaker, Thermal Magnetic Trip, Solar AC Disconnect Switch MCB C20 --- ## 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.hk/products/41374753-110v-ac-2-pole-25a-modular-contactor-2no-din-rail](https://www.desertcart.hk/products/41374753-110v-ac-2-pole-25a-modular-contactor-2no-din-rail) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-08*
