one worked great reordered

I replaced a worn Contactor on a York Model No. H1RA048S06D.The contactor is working okay to power the HVAC Condenser. However, note that the OEM contactor has brass terminal block screws with square washers and the NEW Contactor has steel screws with molded round washers. Fortunately, the screw threads are identical, so I reused the OEM screw with square washer.This is something you may want to consider or at least be aware of going into the replacement because depending on your wiring you may need additional electrical components.Image 1: new Contactor's screw with molded round washerImage 2: HVAC Model LabelImage 3: OEM Contactor with brass screw & square washer

My hvac guy told me the 3 pole relay was bad and told me parts and labor $560.00 I ordered the 3 pole on Amazon got it the next day and my husband installed it in 30 minutes the a/ c is working great

used for motor reversing control

This contactor may have worked but never found out, as it broke within the first time I tightened (not too hard either) the nut on the shunt side of the circuit. The quality of the plastic is laughable for something that is supposed to work with 240 volts.I prefer to buy these things from local Aireco store, but they were closed for the long weekend and Amazon was able to deliver it next early morning so I thought I can save my family from hot weather. With this junk breaking within 1 min, I ended up waiting for Aireco to open and drove down there first thing in the moring. They had much better quality from the brand Mars (see the second pic of it installed), which was almost twice the weight of this junk and it also had much better nut design, which allows for thick wires to slide right through it and also allows you to push the contactor magnet to test, instead of opening two screws and having a risk to touch your screwdriver to the place you would want to be.

Installed new out of the box and this part did nothing but rattle and make an ungodly noise.

It wasnt bad , i wish if the line side had screws to attach the coil power , it would be easier than me have to crimp it
