Migro 2 Pole 40 AMP Heavy Duty AC Contactor Replaces Virtually All Residential 2 Pole Models (2- Year Warranty-High Quality Silver Alloy Content Contactors)

2 year update. This contactor has been running great in south texas heat for 2 years now. Would recommend for a factory replacement. Lasted longer than the original that came with our carrier unit!

I have learned over my life that the air conditioner will only break one time a year; on the hottest/coldest day of the year. Sure enough, Murphy's Law didn't let me down. My 3 ton heat pump unit stopped working on a 117 degree day in Phoenix, and the house quickly became stifling. Fortunately I had purchased the Migro 2 Pole 40 AMP Definite purpose contactor, 2 to be exact. I used one roughly a year ago, and I still have a back up in the event I need one. I inspect the contactor every year before it gets unbearably hot. So far the Migro contactor doesn't chatter, there's no slop, and it pulls in tightly when the coil is energized. I strongly encourage you buy one, or actually two. I have no regrets buying this two pack as the knowledge of having with a contactor in the event I need one is very reassuring. I recommend you to also have a back up fan and run capacitor(s), as they two will pop on very hot/cold days, and no one wants to experience that while having to them delivered, have some company over-charge you, or worse - knowing that for 45 bucks you could be up and running, but because you didn't buy these, now you're at the mercy of others.

It appears to be high quality. I'm using it to run a 1hp motor on my balancer with a momentary contact switch to power the coil. When I first powered it up it was on until I pushed my switch a couple of times. I don't know if that was the switches fault or the contactor. Working good ever since.

Replaced the old Honeywell relay on my RHEEM RAMA-048JAZ. Before replacing, it took a few minutes to start the AC and finally it got to the point where the outdoor fan would not shut off. After replacing powering the AC on and off is almost instantaneous. Would be helpful to have a wiring diagram of some sort but if you can understand electronics it’s not too bad. There are connectors that are connected the two ends of the coil. The L1 connects to T1 and the L2 connects to the T2 once the coil is powered. Time will tell how it lasts, but most components are made in china now so it is what it is.

Works for my project

Ive been buying these contactors and they are very well made. I havent had any issues with none of them and ive bought over 50 for my business.

Hello, We did an air condition rebuild on a very old unit. We got a spare contacter to keep around in case our air stops running. They have points inside that eventually wear out and they are easy to install. Transfer one wire at a time not to mix them up.

Bolted right up on my 3 ton Goodman unit--mounting holes match.Nice as it has both types of connections for 220vac side--take your pick: (1) insert wire and pinch with a screw type and (2) standard HVAC lug push-on connectors (faston).My unit had (1) for the incoming power and (2) for the outgoing power.The 24vac coil lines are standard fastons.Nice and quiet operation. The old would buzz (even when new)
