Selecting relays, contactors & industrial switches gets complicated quickly when similarly priced contactors have very different coil voltages and pole counts. The practical payoff is simple: narrow the choice by the control voltage first, then choose the pole configuration and amperage that fit the electrical job. In this group, that means deciding among 24V, 110V, and 220V coils-not treating the four units as interchangeable.
Quick take
The 1 Pole 40 Amp 24 VAC Coil AC Contactor is the listed 24V option with the highest current rating, but it is a one-pole configuration. The 2 Pole 30 Amp 24 VAC Coil AC contactor also uses a 24 VAC coil and moves to two poles at a 30 amp rating. For three-pole needs, the Brand New 3 Pole AC Motor Contactor CJX2-3210 pairs a 110V coil with 32A, while the AC Contactor -1801 combines three poles, 32A, and a 220V coil. Listed prices run from USD 21.99 to USD 28.79, a USD 6.80 spread.
Listed-price comparison
| Contactor | Coil voltage | Pole configuration | Current rating | Listed price | Price bar |
|---|---|---|---|---|---|
| AC Contactor -1801 220V 32A | 220V | 3P | 32A | USD 28.79 | |
| 1 Pole 40 Amp 24 VAC Coil AC Contactor | 24 VAC | 1P | 40A | USD 23.99 | |
| Brand New 3 Pole AC Motor Contactor CJX2-3210 | 110V | 3-pole | 32A | USD 21.99 | |
| 2 Pole 30 Amp 24 VAC Coil AC contactor | 24 VAC | 2P | 30A | USD 22.99 |
Decision matrix
- Need a 24 VAC coil and one pole: Choose the 1 Pole 40 Amp 24 VAC Coil AC Contactor. Its 40A rating is the largest in this comparison, but its single-pole layout is a defining constraint.
- Need a 24 VAC coil and two poles: The 2 Pole 30 Amp 24 VAC Coil AC contactor is the direct match, with a 2P layout and 30 amp FLA rating.
- Need three poles with a 110V coil: The CJX2-3210 is the clear fit: 3-pole, 32A, and 110V AC coil voltage.
- Need three poles with a 220V coil: Select the AC Contactor -1801, which is listed as a 32A, 50/60Hz, 3P contactor with a 220V coil.
Product notes
AC Contactor -1801 220V 32A 50/60Hz Coil 3P 3 Phase Rail Motor Controler Rail

This contactor suits a control setup calling for a 220V coil alongside a three-pole, 32A contactor. Its title also specifies 50/60Hz operation, and the description identifies three poles plus one normally open contact. That combination makes it the focused choice here for a three-phase motor-control role using 220V coil control. It is listed as new and includes an AC contactor. The trade-off is its higher listed price within the group, and its 220V coil separates it from both 24 VAC choices and the 110V CJX2-3210. Choose it for the stated 220V/3P/32A combination rather than as a substitute for the lower-voltage coil models.
1 Pole 40 Amp 24 VAC Coil AC Contactor 1P 40A 24V 50/60Hz AC Motor Contactor Rep

For a 24 VAC coil application where a one-pole contactor is appropriate, this is the current-capacity-led option: it is listed at 40A and 50/60Hz. The copper construction and black housing are also specified, while its single-phase design aligns with the one-pole product title. Its condition is listed as new open box. The limitation is inherent in the 1P format: it does not provide the two-pole layout of the 30A 24V contactor or either three-pole layout. This is the pick when the 24V coil and 40A single-pole combination are the central requirements, not when the application calls for multiple poles.
Brand New 3 Pole AC Motor Contactor CJX2-3210 32A, Coil Voltage 110V, NO

The CJX2-3210 is the strongest match for a 110V AC coil requirement with three poles and a 32A maximum amperage. It is identified as a definite-purpose contactor, and its title calls out a normally open configuration. The product description also notes a spring-loaded rail locking lever, while the compact design language may appeal where a smaller contactor format is preferred. Its key limitation is voltage specificity: this is neither a 24 VAC coil contactor nor the 220V-coil alternative. It also carries a 32A rating rather than the 40A shown on the one-pole 24V model. Choose it when 110V coil control and a 3-pole format are the required pairing.
2 Pole 30 Amp 24 VAC Coil AC contactor 2P 30A 24V 50/60Hz AC Motor Contactor

This is the straightforward choice for a 24 VAC, two-pole contactor rated at 30 amp FLA. The title and description consistently specify 50/60Hz, and the description names copper terminal contacts and a copper coil. It is also described for air-conditioner compressor condenser-unit contactors, which gives the 2P/24V/30A configuration a clear use-case identity. Compared with the other 24V coil contactor, its limitation is the lower 30A rating and two-pole form instead of 40A and one pole. It is also not the option for a 110V or 220V coil. Pick this model when two poles and 24 VAC control matter more than the higher 40A rating.
Final recommendation by use case
Choose the 1 Pole 40 Amp 24 VAC Coil AC Contactor for a 24V, one-pole requirement at 40A. Choose the 2 Pole 30 Amp 24 VAC Coil AC contactor for the comparable 24V control voltage in a two-pole, 30A format. For three-pole contactors, the decision is primarily coil voltage: select the CJX2-3210 for 110V and the AC Contactor -1801 for 220V. The CJX2-3210 has the lowest listed price, while the -1801 is the 220V three-pole route.
