Choosing a replacement contactor for an air conditioner, heat pump, or motor circuit comes down to matching coil voltage, pole count, and the current your equipment draws. Both of these 2-pole contactors run on a 24V coil, but they sit at different points in the 30-to-40-amp range, and their listings highlight different build details. The key is to find the one that matches your system's current specification.
Quick verdict
If your circuit calls for 40 amps, the Dp Contactor 2 Pole 40 Amp 24V Coil model is the lower-priced pick at $19.99. If you'd rather have a 30-amp listing with clearly described material details, the 2 Pole 30 Amp 24 VAC Coil contactor comes in at $22.99. Both share a 2-pole, 24V coil layout, so the choice comes down to current rating and the specifics that matter to you.
Side-by-side comparison
| Product | Listed Price | Coil | Poles | Current Rating | Notable Spec |
|---|---|---|---|---|---|
| Dp Contactor 2 Pole 40A 24V Coil | $19.99 | 24V | 2 | 40A | UL in title |
| 2 Pole 30 Amp 24 VAC Coil Contactor | $22.99 | 24VAC | 2 | 30A | Flame-retardant shell |
Where each stands out
The higher-current model fits when you need extra capacity and want the lower listed price. Its description also points to use as a heavy-duty enclosed replacement for Carrier, Bryant, Day & Night, and Payne contactors in the 40A/30A range with 24V coils.
The 30A model fits when you want a clearly specified replacement with a 24VAC coil, 50/60Hz operation, and an explicit operating temperature range. The listing spells out material details like pure copper coil and flame-retardant shell, which can be helpful if you're comparing component construction.
Product notes
Dp Contactor 2 Pole 40 Amp 24V Coil HVAC 50A 40A 30A AC Motor Air Conditioner UL
This 2-pole contactor uses a 24V coil and puts a 40A rating at the top of the title. The listing calls out heavy lug screws, four 1/4-inch quick-connect terminals, fully enclosed contacts, and copper contact points, so it's aimed at HVAC and motor replacement work. It's also positioned as a heavy-duty replacement for Carrier, Bryant, Day & Night, and Payne contactors in the 40A/30A range with 24V coils. The one catch is the title's mix of 50A, 40A, and 30A, so the intended replacement rating isn't as clean as a single-number label. If your system's spec clearly says 40A, this model gives you a direct match.
2 Pole 30 Amp 24 VAC Coil AC contactor 2P 30A 24V 50/60Hz AC Motor Contactor
This contactor is rated at 30A with a 24VAC coil and 50/60Hz operation. The listing includes a temperature range of -40°C to +65°C, copper terminal contacts, a pure copper coil, and a flame-retardant shell. It's described as a direct replacement for air conditioner compressor and condenser unit contactors, with no wiring or adapter changes needed. The trade-off is the 30A rating, so if your circuit asks for 40A, this isn't the model to order. For a straightforward 30A replacement with explicit component details, this listing is the more descriptive of the two.
Final choice by use case
For a 40A-rated HVAC or motor replacement, the Dp Contactor 2 Pole 40 Amp model is the one to pick. For a 30A-rated contactor with clear material specifics, the 2 Pole 30 Amp 24 VAC Coil model is the straightforward choice. Match the current rating to your equipment's spec, and you'll land on the right one.
