## Description

This contactor is a heavy duty enclosed replacement for all one pole contactors rated at 40 Amps or less which have 24 volt coils. This contactor is rated at 40 Amps and has a 24 Volt coil. This contactor has a heavy lug terminal and 4 male quick connect ¼” terminals on each line voltage connection to provide maximum wiring flexibility. The two terminals for the low voltage coil each have double ¼” male quick connects. The contact mechanism is enclosed to keep out insects and debris, but the visible plunger provides positive verification that the contacts are pulled in. The coil is encapsulated with no exposed tape wrapping. The mounting base measures 2-5/16” X 1-15/16” with four oblong mounting holes 1-5/8” x 1-5/8” on center. There are also four slots in the base to provide many mounting options. This part replaces most residential one pole contactors. The 24 volt coil is rated at 6 VA sealed / 31 VA inrush. This part is covered by the exclusive Protactor two year limited replacement policy. If this part fails within two years from date of purchase, return the defective part and a copy of the original invoice to the place of purchase for replacement. Contact the authorized Protactor dealer that you purchased the part from for details. Original equipment manufacturer's brand name(s) and part numbers are used for identification purposes only. This item is supplied by Protactor and meets or exceeds original equipment specifications.

Review: Easy Fix - Great product that worked out fine as a replacement. I was sure to disconnect the power and discharge the capacitor. I took a picture of the connections before disconnecting and removing the old contractor. The markings on the terminals of the old and new part were completely different. I was just careful to connect the primary power to the side labeled 440v and the control wires to the side labeled 24v. The main control wires on my AC unit had terminals whereas this new part had screw connections for the control wires just like the high voltage side. I had to cut the terminals off, strip the wires and insert them into the holes and tighten the screws. On my unit all the yellow control wires went on the right. I then had to connect all the terminals properly on the right, left and top. One of the terminals was rusted and broke off. Luckily I had a terminal and crimper for it. Everything went back together great and once I closed everything up and reconnected the power the air conditioner worked fine. Pretty easy for what the AC repair company wanted to charge me over $500.
Review: Great part - Got my AC up and running. Save several hundred dollars.

### ⭐⭐⭐⭐⭐ Perfect Replacement-Upgrade Contactor
*by D***D on July 25, 2022*

I have a 3-ton Amana A/C unit that is 23 years old. Over the past few weeks, I was aware of the HVAC system being Off, but that the compressor outside was still running, building frost on the cold side line. At first I just went to the Breaker Box and shut off the A/C breakers. Then I took the side cover off the A/C unit outside and "rapped" on the contactor. After 2 or 3 hits, the compressor shut off. In my case, the contactor was working well enough to turn On the unit, but the contacts would weld themselves tight together and not allow the unit to turn Off. This unfortunately caused many nights of poor sleep as I never knew when the next time the contactor would fail "On" again. As you are already aware, Amazon carries an exorbitant collection of contactors from which to choose, but I drilled my decision down to this Protactor contactor. In case you don't already know, basically all of these contactors are built with the same footprint and size, with the main differences being the coil operating voltage (24, 120, or 220VAC), the contactor (relay) contact ratings (from 25 to 40 Amp), and the number of poles that are required for the control circuit (1, 2, or 3). My contactor was a simple 1 pole circuit with a 24v coil and contacts rated @ 25 Amps for FLA (Full Load Amps). Therefore, if I can upgrade to a 40 Amp FLA contactor, it allows the contacts to live a much longer life with 60% greater contact area. I received this 40A Protactor within 2-days after ordering it and installed it right away. My A/C compressor and fan are now running better than ever! I really mean it! Before, with the worn out original contactor, the compressor used to literally groan and growl especially during the first few minutes of operating. Now, with the 40A Protactor in place, there is none of that, very smooth and quiet, as it should be. I thought I might need a new compressor, but now I realize that the old contactor was wasting energy across the contacts and not allow full voltage and current to the compressor unit. The A/C appears to also be running less in duration and less often, due to improved operation efficiency. My family is delighted and impressed that I was able to repair our A/C system with a part that cost less than $21 w/ Tax. Now no more worries about the contactor sticking in the On position! I totally recommend this contactor for anyone in a similar situation. It is worth its weight in gold!
