When you need a contactor for an air conditioner, heat pump, or motor control circuit, the two decisions that matter most are the coil voltage and the number of poles. Pick the wrong 24V coil for a 110V control circuit, or a 2-pole where a 1-pole belongs, and the contactor won't do its job. These four new contactors span 1-pole, 2-pole, and 3-pole layouts, with coil voltages from 24V to 110V and listed prices from USD 17.99 to USD 21.99.
Quick take
The lowest listed price belongs to the 1-pole 40A unit, while the most expensive option is the 3-pole 110V contactor. If you need a straightforward 24V single-pole replacement, the 1-pole 40A and the Packard C130A both fit. For a 2-pole 24V setup, the Migro DP contactor is the only 2-pole choice. And if your control circuit runs at 110V and you need three poles, the CJX2-3210 is the sole match.

Decision matrix
- Choose the 1-pole 40A 24VAC coil contactor if your HVAC or refrigeration system uses a 24V control circuit and you need one pole with 40A FLA. It is the only unit here with a 40A 1-pole rating and a 24VAC coil.
- Choose the Packard C130A if you want a 1-pole definite purpose contactor from a named brand and 30 FLA / 40 RES is enough. It is listed for split system and heat pump applications.
- Choose the Migro DP 2-pole 40A if you need two poles with a 24V coil and 40A FLA. The description highlights enclosed contacts and copper contact points.
- Choose the CJX2-3210 if your control voltage is 110V and you need three poles for starting AC motors. It is the only 3-pole option and the only 110V coil in this lineup.
Definite Purpose Contactor, 1 Pole, 30 Amps, 24 Coil Voltage, C130A

This Packard C130A is a 1-pole definite purpose contactor with a 24V coil and a 30 FLA / 40 RES amp rating. It is explicitly listed for central air conditioner, split system, dual fuel split system, and heat pump split system applications, which makes it an easy match for common HVAC service replacements. The description also mentions lug, spade, and protective cover terminal options. The limitation is that if your system draws more than 30 amps continuous, the 40A contactors in this comparison are more appropriate. It also has only one pole, so a 2-pole or 3-pole switching setup would need a different unit.
Brand New 3 Pole AC Motor Contactor CJX2-3210 32A, Coil Voltage 110V, NO

The CJX2-3210 is the only 3-pole contactor here, rated at 32A with a 110V AC coil. Its description calls it a universal AC motor contactor for starting and controlling AC electric motors, and it includes both NO and NC options. The compact design and spring-loaded rail locking lever are also mentioned. The main drawback is that the 110V coil will not work in a 24V HVAC control circuit, so you need to confirm your coil voltage before choosing it. It is the only option with a 110V coil, which narrows its use to 110V control circuits.
Dp Contactor 2 Pole 40 Amp 24V Coil HVAC 50A 40A 30A AC Motor Air Conditioner UL

The Migro DP contactor provides two poles, a 40-amp FLA rating, and a 24V coil. The description says it is a heavy-duty enclosed replacement for Carrier, Bryant, Day & Night, and Payne single-pole contactors rated at 40 or 30 amps with 24V coils, though this unit itself is 2-pole. It uses enclosed contacts and copper contact points. The limitation is that if your application truly needs a single-pole configuration, this 2-pole unit may not be the correct electrical replacement; you would need to match your system's pole count and wiring. For a 2-pole 24V circuit, though, this is the only 2-pole contactor in the lineup.
HVAC Motor Contactor 1 Pole 40A 24VAC Coil for AC Heat Pump Refrigeration UL

This 1-pole contactor is rated at 40A FLA and 50A resistive load with a 24VAC 50/60Hz coil. The description positions it for air conditioners, heat pumps, and refrigeration systems, and it works with devices up to 600VAC. The copper construction is noted in the attributes, and the title includes UL. The limitation is that it has only one pole, so it won't handle 2-pole or 3-pole switching. Also, the brand is not identified, so if a named brand is important to you, the Packard C130A is the alternative among the 1-pole options.
Final recommendation by use case
For a 24V single-pole replacement, choose the HVAC Motor Contactor 1 Pole 40A 24VAC Coil when you need the higher FLA and a UL marking in the title. If you prefer a named brand and 30A is enough, the Packard C130A is the direct alternative. For a 2-pole 24V circuit, the Migro DP 2-pole 40A is the unit to use. And for a 110V control circuit with three poles, the CJX2-3210 is the only match in this group.
