Perfect for HVAC, motor, pump, and lighting control, it ensures full circuit isolation and professional-grade safety compliance, making it an essential upgrade for modern electrical systems. ## Description Product description The miniature AC contactor is mainly suitable for power systems with AC 50Hz/60Hz, rated operating voltage up to 400V and rated operating current up to 125A, in utilization category AC-1 (non-inductive or low-inductivity loads, resistance furnaces, household appliances and similar low-inductivity loads), used for control circuits, household motor loads. Domestic contactors are not used to interrupt short-circuit current, so appropriate short-circuit protection devices (such as small circuit breakers) should be chosen. Comply with IEC61095, GB17885 standards. IEC60947-4-1, GB/T 14048.4. HC1 Series AC Contactor Specifications FUNCTION AND APPEARANCE Modular control device with compact size. Rail-mounted, standardized dimensions, and enhanced safety. Features a direct-acting inverted design, allowing combined installation with miniature circuit breakers in control and lighting panels. Terminal Design Tunnel-type terminals ensure simple, reliable wiring with a double-clamp structure for secure conductor retention. Status Indication Clear ON/OFF feedback via a mechanical color indicator (non-LED) that moves upon coil energization. Safety Housing Flame-retardant thermoset shell resists ignition—exposed to flames, it chars gradually without sustained combustion. Note AC contactors are designed for AC power input, with key components like electromagnetic and contact systems tailored for AC characteristics. They must not be powered by DC, as they only operate stably within specified AC voltage ranges. When Using Class 2 Contactors:If contactors or contactors and circuit breakers are installed side by side, spacing plates must be added between them to ensure proper heat dissipation.Derating is required if the internal temperature of the distribution panel exceeds limits. Review: Well Made - Great contractor. It is well made and it works. Review: Alexa, Turn On My Heater at 2 am, Off at 6 am. - My garage heater is 220 volts but Alexa/Tuya power switches are only 110. I solved the problem by installing this contactor inside the heater cabinet. Now the 110 volt Alexa/Tuya device sends power to the contactor which switches the 220 heater on or off. ## Features - 【2-Pole 2NO Heavy-Duty Switching】Features 2 Normally Open contacts for independent dual-circuit power switching. Designed for high-capacity loads requiring simultaneous make/break operations - 【110V AC 25A Rated Current】Rated 110V AC 25A (AC-7a 25A / AC-7b 9A). Features 1.2W max power, 500V insulation withstand (Ui), and 400V operating voltage (Ue)—reliable for resistive and inductive loads - 【DIN Rail Ready – Plug & Play】Snaps onto standard 35mm DIN rail for quick panel installation. Compatible with AWG 10-4 flexible cords for easy wiring alongside breakers - 【110V AC ONLY – Not DC Compatible】Designed exclusively for 110V AC systems. NOT for DC use. Always use with short-circuit protection (fuse/MCB) and maintain proper spacing for heat dissipation - 【Water Heater & Lighting Control】Optimized for resistive loads such as water heaters and lighting panels. Both NO contacts ensure reliable power delivery with minimal contact wear—ideal for commercial and industrial applications ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.7 out of 5 stars 165 Reviews | ## Images ![Baomain 110V AC 2-Pole Modular Contactor, 25A 2NO Normally Open, DIN Rail Mount for HVAC, Motor, Pump & Lighting Control BCT-25/20,HC1-25/20-110VAC - Image 1](https://m.media-amazon.com/images/I/51ET3o8eyLL.jpg) ![Baomain 110V AC 2-Pole Modular Contactor, 25A 2NO Normally Open, DIN Rail Mount for HVAC, Motor, Pump & Lighting Control BCT-25/20,HC1-25/20-110VAC - Image 2](https://m.media-amazon.com/images/I/611dwhKhWrL.jpg) ![Baomain 110V AC 2-Pole Modular Contactor, 25A 2NO Normally Open, DIN Rail Mount for HVAC, Motor, Pump & Lighting Control BCT-25/20,HC1-25/20-110VAC - Image 3](https://m.media-amazon.com/images/I/51UqRjRSvLL.jpg) ![Baomain 110V AC 2-Pole Modular Contactor, 25A 2NO Normally Open, DIN Rail Mount for HVAC, Motor, Pump & Lighting Control BCT-25/20,HC1-25/20-110VAC - Image 4](https://m.media-amazon.com/images/I/61HqsKu4zDL.jpg) ![Baomain 110V AC 2-Pole Modular Contactor, 25A 2NO Normally Open, DIN Rail Mount for HVAC, Motor, Pump & Lighting Control BCT-25/20,HC1-25/20-110VAC - Image 5](https://m.media-amazon.com/images/I/51A6uHQYPXL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Can this stay energized for very long periods of time without heating up?** A: We are using them on pieces of equipment for 24/7 operation without any problem. I haven’t felt the temperature, but I don’t think that would be a problem. Usually it is the switching that limits the life on these parts. **Q: Will this support 10 AWG?** A: I believe #10 will fit, but don’t over tighten the screw, as it may break the frame. I used #12 jumper, then spliced it to the larger wire. **Q: Do you have a test report and certificate of conformity for this product?** A: no **Q: what is the current drawn by the 110V AC coil when energized?** A: It is .3 amp @ 120 volt coil. Point three amp at 120 volt coil. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well Made *by J***B on March 21, 2026* Great contractor.
