Quick Take
Choosing a contactor from the relays, contactors, and industrial switches family comes down to a few concrete questions. What coil voltage does your control circuit supply? Do you need one pole, two poles, or a reversing starter? And can you use a new unit, an open box, or a used one? These four contactors answer those questions in different ways, with listed prices spanning from $19.99 to $289.99.
If you need a new two-pole HVAC-style contactor with a 24V coil at the lowest listed price in this group, the Migro Dp Contactor is the starting point. If a single-pole 40A unit with a 24VAC coil and an open box is acceptable, the 1 Pole 40 Amp Contactor is close behind. For a reversing motor starter with a 120V coil and a 1.6/5A overload relay, the used Allen Bradley is the only reversing starter here. And if you need a new IEC-style contactor with a 220V coil and an auxiliary contact, the Sprecher + Schuh CA7-85-10-220W completes the set.

Product Notes
Sprecher + Schuh CA7-85-10-220W
At the top of the price scale, this new Sprecher + Schuh contactor is built for a 220V coil and includes one normally open auxiliary contact. It suits both standard and safety IEC contactor layouts, and can be base mounted or snapped onto a 35mm DIN rail. It carries horsepower ratings of 30 HP at 230V and 60 HP at 460V three-phase. The reason to choose it is the 220V coil plus the side-mounted auxiliary contact in a new unit. The limitation is the cost at USD 289.99, which is far above the other three options here, so it makes sense only when the application truly needs this IEC-style configuration.
1 Pole 40 Amp 24 VAC Coil AC Contactor
This compact contactor gives you a 40A single-pole switch with a 24VAC coil and AC current rating. It is built with copper contacts, has a black housing, and weighs about 0.24 kg. The unit is New - Open box, meaning the packaging was opened for pictures; the contactor itself was wrapped in the box. At USD 23.99, it is the second lowest listed price in this group. Choose it when you need a single-pole 24V coil contactor and don't mind an open-box unit. The limitation is that it switches only one pole, so two-pole switching needs are outside its scope.
AB 100-C09*10 Reversing Motor Starter
This Allen Bradley unit is a reversing motor starter built around the 100-C09 contactor, with a 120V coil and a 1.6/5A overload relay. It includes the connector wire between the two contactors. At USD 74.99, it sits in the middle of the price spread. Choose it when you need a reversing starter with overload relay protection for smaller motor loads. The limitation is the used condition; it is not a new unit, and the 1.6/5A overload relay range keeps it aimed at smaller motor applications. If your control circuit needs 120V for reversing duties, this is the only product in this comparison built for that.
Dp Contactor 2 Pole 40 Amp 24V Coil
This Migro contactor is new, two-pole, 40A, with a 24V coil. It sells at USD 19.99, the least expensive listed price in the group. Its construction fits definite-purpose HVAC replacement work, with heavy lug screw terminals and four 1/4-inch male quick-connect terminals. It is aimed at air conditioner and motor contactor duties. Choose it when you want a new 24V coil contactor with two poles and the least expensive listed price. The limitation is that it is positioned for HVAC-style applications rather than as a general-purpose IEC contactor, so that distinction matters if your project requires IEC-style construction.
Final Recommendation
For an HVAC and AC motor contactor role with a 24V coil and two poles, the Migro Dp Contactor is the new two-pole option at the bottom of the price range. If you need a reversing starter with a 120V coil and an overload relay, the used Allen Bradley is the product that matches that job. If your control circuit runs on 220V and you want a new IEC-style contactor with an auxiliary contact, the Sprecher + Schuh is the one to choose. The 1 Pole 40 Amp 24 VAC unit is a practical option when one pole is enough and an open box is acceptable.
