Baomain 220V AC 2-Pole Contactor
The Baomain BCT-50/20 is a 2-pole, normally open contactor rated for 50A at 220V AC. It features a compact DIN-rail-ready design, making it suitable for control panels and HVAC installations requiring a 50A capacity with 220V operation. It lists 50A full-load current (AC-7a) and 20A resistive load, with a 500V withstand rating. This model emphasizes ease of integration with standard circuit breakers and heat management accessories.
SunLee 2 Pole 40 Amp Contactor
SunLee provides a 2-pole contactor with a 120V coil and a 40A full-load rating. It is designed to replace smaller 2-pole contactors used in air conditioners and heat pumps, with class F insulation for coil protection. This option is suitable for systems where the control voltage is 120V and the load requirements align with 40A FLA.
CGele 2 Pole 40A 240V Contactor
CGele’s 2-pole contactor operates at 240V with a 40A coil current and a 50A resistive rating. The 240V coil makes it compatible with many HVAC systems, including condenser units. Features include silver alloy contacts, copper windings, and durable housing designed for harsh environments.
CGele 2 Pole 40A 24V Coil Contactor
This 24V coil version from CGele is a 2-pole contactor rated at 40A (FLA) with a 50A resistive load. It supports devices up to 600V and emphasizes reliable operation in variable environments. It pairs well with 24V control circuits common in modern HVAC equipment.
CGele 2 Pole 40A 24V Coil Contactor (Pack)
Another CGele 2-pole option with a 24V coil, rated at 40A FLA and 50A RES. This model emphasizes durable contacts and reliable performance in HVACR contexts. It is suitable where a 24V control signal is available and 40A load is required.
Protactor 2 Pole 40 Amp Contactor
Protactor offers a 2-pole, 40A contactor with a 24V coil and a two-year replacement policy. It is UL listed and designed to replace common 2-pole contactors with similar amp ratings, making it a compatible choice for standard HVAC installations needing dependable switching.
Buying Guide
Key considerations when selecting a 2-pole, 50A-capable contactor include coil voltage compatibility with the control circuit (24V, 120V, or 240V), full-load current rating (FLA) versus resistive rating (RES), and whether the device is suitable for HVAC, refrigeration, or motor loads. For 50A service, ensure the RES rating and any applicable UL listings match your equipment. Durability features such as copper windings, silver contacts, and flame-retardant housings improve long-term reliability in harsh environments. DIN rail or panel mount compatibility can simplify installation in existing control panels. Always verify coil insulation class and operating temperature range for your climate. Compare devices on voltage compatibility, coil type, and mounting options to find a model that aligns with your system’s electrical design and safety standards.
