When an air conditioner or heat pump compressor stops cycling, the motor contactor is often the part to blame. The decision here comes down to pole count, coil voltage, and load rating, because these two new contactors are not interchangeable. In the relays, contactors, and industrial switches space, you have a 2-pole unit and a 1-pole unit, and the right pick depends on your system's control voltage and how many load circuits you need to switch.
Quick verdict
If your setup needs two switching poles, the HIATSU 2-Pole Air Conditioner Contactor is the clearer choice. If you need a single-pole contactor with a stronger current rating, the HVAC Motor Contactor 1 Pole is the better fit.
At a glance
| Product | Listed price | Price bar | Key specs |
|---|---|---|---|
| HIATSU 2-Pole Air Conditioner Contactor | USD 13.92 | 2-pole, 30A FLA, 120VAC coil, copper, CE and RoHS certified | |
| HVAC Motor Contactor 1 Pole 40A | USD 17.99 | 1-pole, 40A FLA, 50A resistive, 24VAC 50/60Hz coil, copper, UL |
Where each product wins
- The HIATSU is the better fit for systems that need two separate load circuits switched from one contactor. It also carries the lower listed price in this pairing.
- The HVAC contactor suits installations where one higher-capacity switched circuit is enough, with a single-pole design that simplifies wiring and installation.
Product notes
HIATSU 2-Pole Air Conditioner Contactor
The HIATSU earns its place when your setup calls for two-pole switching. With a 30A FLA rating and a 120VAC coil, it can switch two load circuits through one contactor, which is helpful in conventional air-conditioner contactor duty. It is CE and RoHS certified and built with copper, so the material matches the more expensive option. The main limitation is that the HIATSU's full-load amperage tops out at 30A. If your compressor or fan motor needs 40A at full load, the HIATSU is not the right capacity. At USD 13.92, it is the lower-priced of the two products in this head-to-head.
HVAC Motor Contactor 1 Pole
The HVAC Motor Contactor is the stronger candidate for higher-current, single-circuit loads. It carries a 40A full-load rating, a 50A resistive load rating, and a 24VAC 50/60Hz coil, and is UL listed for safety. With a single pole, it simplifies wiring and installation in systems that only need one switched line, which is why it suits many heat pump and refrigeration contactor applications. The limitation is on the other side: there is only one pole, so it cannot handle two separate circuits in one unit. Its listed price is USD 17.99, higher than the HIATSU in this comparison.
Final choice by use case
- Choose the HIATSU 2-Pole Air Conditioner Contactor for two-circuit switching setups.
- Choose the HVAC Motor Contactor 1 Pole for single-circuit switching when you need more current capacity.
