Replacement parts number: 45GG20AF,HCCY2XT04GG, C240B, DP401202. Compatible with:Packard, White Rogers, Packard, Fasco, Mars, C230B/ TJT30A120V2P/17325/PC230A/H230A/90-244 Review: Perfect. So far so good. - Perfect for my project. Small form factor with spade & screw terminals Review: Great AC relay for projects - I needed an Alexa-enabled heavy duty relay, and nothing really exists to switch heavy loads. Don't believe manufacturers who say theirs can switch large motors and such - reviews will show melted switches. So, I decided to build my own, using this relay to switch the heavy load - 15A, but a large inductive (motor) load. This appears to be a really nice, heavy-duty relay, and seems to work well. I removed the spade lugs on the switched relay connections as I'm only switching one outlet, and prefer direct connection to 14 gauge copper. I did use the spade lugs for the relay coil connection, with a Tapo Alexa-enabled smart switch driving the coil power. Then, put it all in a metal box (see photo, sans cover). For the smart switch, one nice feature of the Tapo switches is that you can set them to be normally off, so after a power outage, the switch will remain off until turned on - the switch default is to remember the last power state. ## Features - 2 Pole 40 Amp 120Volt coil - 40 FLA Amp Rating - 2 Pole - 120 Volt Coil.

This 40A contactor is a safe upgrade for a 30A unit, provided the Coil Voltage (120V) and Poles match. Rule: Coil voltage must be exact; Amps can be higher, but never lower than your original one. **Q: My equipment runs on 240V, but I have a 120V control source. Will this work?** A: Yes. The "120V" refers to the Coil (control) voltage only. The power poles (contacts) are rated up to 600V, so they can easily and safely switch a 240V load while being triggered by a 120V source. **Q: Can I use this to control a bank of grow lights with a timer?** A: Yes, absolutely. This is ideal for switching high-power lighting loads (like HPS, MH, or LED grow lights). You can connect the 120V coil terminals to a standard wall timer or smart plug to automate your lighting setup safely. **Q: Is this suitable for a sump pump or pool pump motor?** A: Yes. It is rated for 40 Amps, making it heavy-duty enough to handle the high startup current (inrush) of pump motors. Just ensure your control switch (float switch or timer) provides a 120V signal. **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 ### ⭐⭐⭐⭐⭐ Perfect.

It was a direct replacement for my old unit and installed easily in my HVAC system. The contacts feel solid, and the unit has been working quietly and reliably so far. Great value for a 40 amp contactor—no issues after weeks of use.” ## Frequently Bought Together - SunLee 2 Pole 40 Amp contactor 120v coil UL 2 pole Lighting Load 50 AMP Contactor equivalent to 42CF15AF Condenser Compressor Contactor - SunLee 3 Pole 40 Amp contactor 120V coil UL DP Contactor HVAC Contactor A2L Compliant 42CF35AF equivalent - BUD Industries JB-3956-KO Steel NEMA 1 Sheet Metal Junction Box 8 L x 6 W x 4 D, Gray --- ## 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.us/products/748145265-2-pole-40-amp-contactor-120v-coil-ul-2-pole](https://www.desertcart.us/products/748145265-2-pole-40-amp-contactor-120v-coil-ul-2-pole) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-10-12*
