Copeland Comfort Control (Alco) 057531 Coil

The Copeland Comfort Control (Alco) 057531 Coil is a professional-grade 208-240V solenoid coil engineered for high-cycle reliability in commercial refrigeration and HVAC systems. As an AMS series open frame coil, this component features a 12-watt power rating and is designed specifically for compatibility with 110RB, 200RB, 240RA, and 540RA solenoid valves. The Class F insulation provides a high thermal ceiling, rated up to 155°C (311°F), ensuring stable performance in demanding environments prone to vibration and mechanical shock.

This OEM replacement coil utilizes standard 1/4 inch spade terminals for rapid field installation and secure electrical continuity. Whether you are servicing a chiller, boiler, or fan coil unit, the 057531 208-240V 60Hz coil delivers the precise magnetic force required for consistent valve actuation. Its compact, interchangeable housing design allows for versatile application across various Alco valve bodies, making it a staple for every service truck's inventory.

Key Benefits for Technicians:

• Direct OEM Compatibility: Specifically engineered for the Alco AMS series, ensuring exact physical fit and magnetic pull.
• High Temperature Resilience: Class F insulation prevents premature coil burnout during continuous duty cycles.
• Standardized Electrical Connections: Features dual spade terminals for easy integration with existing wiring harnesses.
• Universal Frequency Support: Operates efficiently at both 50/60 Hz, providing flexibility for different regional power grids.
• Robust Construction: Encapsulated windings protect against moisture infiltration and environmental degradation.

Common Questions:

Will this coil fit an ASC2 style housing?
This is an AMS series open frame coil. While the internal coil dimensions are similar, the 057531 is designed for spade connections rather than the DIN plug found on ASC2 coils. Verify your enclosure type before installation.

Can I use this 208-240V coil on a 120V system?
No, using a 240V solenoid coil on a 120V circuit will result in insufficient magnetic force to lift the valve plunger (MOPD failure). Always match the coil voltage to the system's control circuit.

Is this coil compatible with DC applications?
The Alco 057531 is an AC-rated coil. For DC applications, the MM series is recommended to ensure proper opening power and prevent overheating.
