PackardC240B Packard Contactor 2 Pole 40 Amps 120 Coil Voltage

It does exactly what it was supposed to do. When 120v AC power it put through the "sides" of the contactor it closes and connects the circuit. My dust collector draws, according the manual, 20 amps on start up and runs at 15. However my local test claims 20 through out. It does not trip the 20amp circuit breaker.Before noting this and reading well enough I tried a remote control outlet to switch it on and off. Fried it instantly. I was very disappointed. So I got a heavy duty one for a dust collect and it also fried instantly. Turned out the heavy duty was good for 15 amps. That was the reason that I checked it out much more thoroughly. At 40 amps this was capable of carrying so much more than was needed I knew it would burn out.Tis was used to produce a remote controlled dust collector switch. I used the "Woods 32555 Outdoor Remote Control Outlet Converter Kit" as the remote control and the switching element. The remote had a little ring on it that make it easy to add a carabiner. It also had a short cord which normally I think I would have found annoying but for this application was perfect.Add a 25' 12 gauge extension cord and a 6' very cheap green christmas light extension cord and I was all set. Well I also used standard 1/4" blade connectors from Home Depot. < $3 for a pack of 30 I think... I needed 7 total because I messed one up.I cut about 8" off of the end of the cord, was connected to the "sides" of the contactor and then "plugged" into the remote.I used the power cable from the remote receiver/socket to connect to the same side of the contactor as the power-in from the extension cord. So it is powered whenever the cord is plugged in whether the contactor is engaged or not. Then power out from the contact goes to the rest of the 12 gauge extension cord.While the above explanation is perhaps not a review of just the contactor itself it might prove valuable to some. So let me summarize it a bit.I am not an electrician but I was able to do all of this construction in about 30 total minutes. The contactor was very made and very easy to deal with. The fit and finish were perfect for what I was doing. This is switched on and off dozens of times a day over the last 3 months, probably a 1000 total cycles by now, and everything is working perfectly.I would highly recommend this for any type of application or problem like I have having.

I used this to build a smart water heater timer/controller. I had an older mechanical water heater timer, that had failed after many years of reliable use. I wanted to add a smart controller to this, but there does not seem to be one that is ready made for this purpose. I decided to try one of these smart relay switches to control a contactor which controls the power to the water heater. I installed the smart relay switch, a 220v 40a contactor w/110v coil, and a terminal strip into the same box the old mechanical timer was in, and it works like a charm. Now I can add timers using the smart app, and also use voice control with my Amazon echo to turn the water off and on. It would be nice if someone made one of these complete and ready to install. But it's nice that I could build this for under $35. That's about half of what the mechanical timer would have cost to replace, and not I have smart control of it.

I was looking to buy a Contactor to switch my electric water heater on and off depending on the on/off-peak hours from my electric company and it has been holding up great after 5 months of switching 4 times a day during the weekdays for a total of 616 on/off cycles!It is a heavy duty, well-made product; I wouldn't be surprised if it will last me many more years of use. I actually bought a 2nd one to install at my parent's place and theirs is going strong too. It has already saved me over $100 over the months that I've used it! Overall, this was a no-brainer purchase for me; I just wish that I have bought it sooner.

I have my air compressor in my shed about 60 feet from the house so I don't have to hear it run. I had an air line burst in the middle of the night and the compressor ran for hours until I noticed. I used this relay to control the contacts on the compressor to only be active when a low voltage switch is on in the shop. I also put a strip of red LEDs in the shop that turns on when the compressor airs up and off when it's full. If the LED strip stays on too long I can go out to the shed and see if there is a problem. When I'm done working for the day, I flip the switch in the shop and know that the compressor won't turn on even if the tank pressure gets too low due to an air leak.

These contacts work great I have used them to time my pool pump with a small 5 dollar timer for the coil and you can use them for 240 volt or 120 volt. I have also used them for shop vac in my shop using a cheap remote control for the coil control voltage. How ever they don't come with instructions. so just know you control it with 120 volts on the coil and you can put 240 volts on the contacts or 120 volts on the contacts. for a bout 10 dollars you can control a lot of hi amp motors or devices for very low money compared to the prices of already made-up high amp remote control switches.

I installed this contractor on my home water heater. I used it in conjunction with a Kasa smart plug for remote control as well as scheduled control of my water heater. Basically I built a water heater timer. It works great! In fact it worked so well I did the same at my vacation home. Some of the reviews state that the coil noise is loud, not on either of the two I installed. Works fantastic and is quiet.

Did everything as advertised. Some complain that it has a loud hum, but that may be because it is housed in a junction box attached to a wall, which causes the wall to act like a drum head.I installed mine inside a junction box which is mounted on top of my hot water heater by a single 3/4" diameter 2" mounting pole, so it makes very little humming sound.Been operating for two months now without a problem.

I bought several of these to use with zwave switches to automate the hot water heaters. Havn;t gotten around to that but just used the first one of these to control a new Salt chlorinator on the pool. It worked perfectly and if your wire size exceeds what you feel safe putting a solderless connector on, the spades on the contact point can be removed and the screws used.No issues installing, Coil is nice and strong and contacts have a nice solid, satisfying click when activated.

Works great unlike the device it's controlling. Quiet. Installed in furnace room with a wireless switch to voice activate Tesla charger. Even with this upgrade I'm getting 13 miles per hour charge. So slow. Never trust NOT a car salesman. Glad it's a lease.

Parfait, c'est ce que je cherchais pour connecter mon compresseur sur interrupteur intelligent

So far so good!I used this to automate a 240v construction heater I use to keep my gazebo toasty. Simply made line connections and plugged into a homekit compatible smartplug. Named the smart plug “gazebo heat” and now siri will turn on and off by command. I also have it set to shut off at night saving me the large electricity bill when I leave it running for a week! Ouch that one hurt.

It seems to work well with just over a month of use in . Suppose to last 7 million on/off cycles so if it falls short I will update the review. At first though it was very noisy with loud buzzing and I was concerned that it was a dud. However within less than a dozen on/off cycles it went whisper quiet and has been since then. I read somewhere that when they go bad they make noise.

Works great , long lifeAffordable priceI’ve been using this for last 3 years and never have any problems
