Choosing an AC contactor for a motor control setup usually comes down to coil voltage and pole count. In the relays, contactors, and industrial switches space, two options stand out: a compact 1-pole unit with a 24 VAC coil and a 40 A rating, and a 3-pole unit with a 220 VAC coil and 32 A rating. The 1-pole contactor lists at $23.99, while the 3-pole unit lists at $28.79, leaving about $4.80 between them. The right pick isn't about the price gap; it's about matching the contactor to your control circuit and load requirements.
Quick Verdict
If your control circuit operates at 24 VAC and you need a single pole with 40 A current capacity, the 1 Pole 40 Amp 24 VAC Coil AC Contactor is your match. If you're controlling a three-phase motor and need a 220 VAC coil, 32 A rating, and an auxiliary normally open contact, the AC Contactor -1801 220V 32A is the one to choose.
Comparison Table
| Feature | 1 Pole 40A 24V | -1801 3P 220V |
|---|---|---|
| Listed price | USD 23.99 | USD 28.79 |
| Coil voltage | 24 V | 220 V |
| Current rating | 40 A | 32 A |
| Poles | 1 pole | 3 poles + 1 NO |
| Condition | New - Open box | New |
| Material | Copper | Copper |
Where Each Product Wins
- Choose the 1 Pole 40A 24V if your control signal is 24 VAC and you need a 40 A switching capacity in a single-pole design. The open-box condition applies to this unit.
- Choose the -1801 220V 32A if you need three-pole switching with an auxiliary normally open contact, a 220 VAC coil, and a rail-mount form factor.
Product Notes
1 Pole 40 Amp 24 VAC Coil AC Contactor
This 1-pole contactor packs a 40 A rating and a 24 VAC coil into a compact black unit made from copper. It is sold in "New - Open box" condition, with the box opened for pictures. It weighs about 0.24 kg and is intended for AC motor control at 50/60 Hz. The key reason to select it is the 24 V coil, which pairs directly with low-voltage control circuits, plus a higher current capacity than the competing model. The limitations are its single-pole format-it can't handle three-phase or multi-pole switching-and the open-box condition if you prefer factory-sealed packaging.
AC Contactor -1801 220V 32A 50/60Hz Coil 3P
The -1801 features a 220 V coil, a 32 A rating, and 3 poles plus 1 normally open contact. Its title highlights rail-mount use, and the blue unit is "New" with the contactor as the included component. The copper coil supports 50/60 Hz operation, and the design suits long-distance circuit breaking and frequent motor starts. This model wins when you need a three-phase switching solution and an auxiliary NO contact for control logic. The constraints are the 220 V coil voltage-which won't energize from a 24 V signal-and the lower 32 A current rating compared to the other unit.
Final Choice by Use Case
If you're running a 24 VAC control circuit and need a simple, single-pole 40 A switch, the 1 Pole 40 Amp 24 VAC Coil AC Contactor is the one that directly matches your circuit. If you're working with three-phase motors and require a 220 V coil plus an auxiliary normally open contact, the AC Contactor -1801 220V 32A is the better fit. Match the coil voltage and pole count to your installation, and the right contactor becomes clear.
