Product Details

The Trane RLY3372 is an OEM single pole single throw (SPST) start relay designed for use in Trane and American Standard HVAC equipment. This electrical relay features a 50 amp coil capacity and is engineered to provide reliable compressor motor starting in residential and commercial air conditioning systems.

Key Specifications:

  • 50A coil rating with 420 continuous coil capacity
  • 180-195V pick up voltage range (190-200V hot pickup)
  • 60-121V drop out voltage
  • 60 Hz frequency rating
  • 7500 ohm coil resistance
  • SPST (single pole single throw) configuration

Start relays function as electrically operated switches that control higher voltage circuits (typically 120-240V) by energizing a low voltage coil. This relay opens and closes circuits to manage the compressor start sequence in HVAC systems. The RLY3372 has been superseded by part number RLY03372, which is functionally identical with no modifications to the design.

Cross-Reference Part Numbers: RLY03372, RLY-3372, supersedes RLY03150, RLY3150, RLY02227, RLY2227

Everything was perfect! Items came in on time and was also package great.

Had part fast

My commercial fishing boat had an issue after 48years and we lost an exhaust elbow. I emailed barr marine and they said they still make those parts, but they don't sell to the public but explained that there are many that sell the parts I was looking for. Your company had most of them and I purchased from another company to get the all parts I needed for the repair. I'm still amazed that I found the parts I needed and that the original company still makes them. Your site was easy to navigate and shipping times were short . Will direct others to find what they need. Thank you.

Great experience and extremely quick delivery

By my own error and partially how the product was advertised, I believed I was getting a cushion with snaps and not Velcro. I, fortunately, have some stainless snap kits and can resolve the issue. Besides that, everything went fine
