I've never fixed an air conditioner before, but when I took a look at the insides, it didn't look like it would take a rocket-scientist to figure out the problem and remedy it. I was right. A contactor is known as a "relay" in the rest of the non-HVAC world. That's what it looked like to me: a classic low-voltage circuit pressing together contacts for a high-voltage circuit. It was exactly that, and this unit did exactly that, replacing the OEM relay easily. It isn't completely like the OEM contactor. The mounting holes are in a different place, necessitating drilling a couple of holes to mount using the screws from the original contactor. Also, the high-voltage connector lugs aren't exactly like the OEM: the original one had two screw-in contacts for the supply-side wires, and then two screws supporting a wire with a lug on it for the supplied-side. This unit is screw-ins on all four corners. I simply clipped off the lugs on the supplied-side, stripped the wires, and screwed them down. The other wires used crimped-on connectors, and these simply clipped right onto the the lugs of this unit. The last difference is that the relay connectors for the 24VAC control on this unit are north & south on this relay, rather than both on the "west" side like the OEM. So this unit isn't exactly like the OEM, but the difference is insignificant and doesn't affect operation at all. Time will tell how well this unit holds up. If I get 25% of the life the OEM had, I'll be more than happy. Review: AC contactor - desertcart is amazing! I placed my order this morning with same day delivery. At 4:30 I checked my "order status" and could see an interactive map with the delivery truck moving through my neighborhood and then a few minutes later, an image of the package appeared with the package at my door. The AC contactor was an easy installation (took less than one hour). Although the new part looks slightly different from the OEM part, the mounting base fit fine. Wiring of the new contactor looked slightly different (contacts arranged vertical instead of horizontal), it connected without any issues. Energized the system and my AC works fine. Can't beat the price and service. Part appears to be well made. Very happy with the hardware as well as the same day delivery. ## Features - 2 pole, 40 amp and 24v - Contactors meet specifications for devices up to 600 V AC UL approved - Coils have class b insulation, includes lug, spade terminals, and covers - Replaces: Mars 17421 Siemens 45GG20AJ cutler-hammer C25BNB240T Hartland controls HCCY2XQ04GG303 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06X8Z255M | | Batteries | 1 Unknown batteries required. | | Best Sellers Rank | #46,392 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #41 in Motor Contactors | | Date First Available | June 29, 2010 | | Department | Unisex-Adult | | Is Discontinued By Manufacturer | No | | Item Weight | 1.6 ounces | | Item model number | PACKARD - C240A | | Manufacturer | Packard | | Product Dimensions | 2 x 2 x 1 inches | ## Product Details - **Brand:** Packard - **Circuit Breaker Type:** Standard - **Current Rating:** 40 Amps - **Mounting Type:** Unit Mount - **Product Dimensions:** 3"D x 4"W x 3"H ## Images ![C240A Packard Contactor 2 Pole 40 Amps 24 Coil Voltage - Image 1](https://m.media-amazon.com/images/I/61ScReimZsL.jpg) ## Questions & Answers **Q: What kind of wire connectors can I use?** A: The main power terminals screw down in the lug. The coil connection and additional power connectors are 1/4" Quick Connect (QC) terminals. **Q: This contactor makes a high-pitched noise when energized - not very loud, but doesn't seem right. Is this normal?** A: I would get a voltmeter and make sure that the proper amount of electricity is passing through it sometimes coils will make a high pitch sound until they break and believe it or not but just check in with the meter before I would get everybody else involved good luck **Q: which side is common and which side is hot for the 24v?** A: There is no common (white) wire for 220V wiring. Both are black. I used my 2-pole 240Amp 24 V coil contactor for my heat pump and 2 black wires come from the power source and go to the bottom two poles. In the future if you are simply replacing your new with an old contactor, its a good idea to always take a photo of the wiring before you disconnect the old one, so you can easily put all the wires back the same way. **Q: Is this a replacement for a tyco or lennox 20394902 contactor spst,n.o.,24 volt coil** A: If you analyze and compare those contactors, you can say yes it is a replacement. Remember that the quality of the product has a weight in a period of time. With the price of one Tyco you can buy two Packards, but you can see the real difference in the future. It is the equivalent to tell you if this product is the replacement for a Siemens contactor 24 V 40 amps The answer it will be yes too, but the difference of the price is astronomical huge. The final decision depends if you want to change that contactor very often and you will change it, if you have to paid for change the contactor I recommend you to buy a good contactor. The conclusion is technically, yes it is the replacement, remember to check to amps that you require. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked Perfectly *by B***B on July 13, 2017* This replaced an OEM Payne 40Amp contactor.

I had a single contractor (where only one leg of the 240v is switched) but I did some research and found out that most AC contractors that run their own business only stock dual leg contactors to save room on their truck. Some manufacturers state that there is some bleed current that goes though the single leg to keep the motor slightly warm. At least on my model, that is impossible because there isn't a neutral to return that bleed current. Switching a single leg is electrically the same as switching both, unless current is being returned via ground (which in almost all cases is not allowed via code). My AC unit doesn't even have a ground electrical connection. If there is a ground connection, it is to 'earth' via the metal supports that hold up the AC unit in the concrete wall. My unit has been running a few days on this, and had no issues with the contactor. The holes lined up with the old one, just had to unscrew the old one and hook up the new one after pulling the main disconnect. ## Frequently Bought Together - Packard C240A Packard Contactor 2 Pole 40 Amps 24 Coil Voltage - VEXUNGA 10uF 370/440VAC 50/60Hz CBB65 CBB65A Oval Run Start Capacitor 10 MFD 370V/440V Air Conditioner Capacitors for AC Unit Fan Motor Start or Pool Pump or Air Condenser Straight Cool - Packard Contactor C130A 1 Pole 30 Amps 24 Coil Voltage 4.5 Out of 5 Stars 44 --- ## 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.co.th/products/40600383-c240a-packard-contactor-2-pole-40-amps-24-coil-voltage](https://www.desertcart.co.th/products/40600383-c240a-packard-contactor-2-pole-40-amps-24-coil-voltage) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
