Copeland Comfort Control (Alco) 057331 Coil

The Copeland Comfort Control (Alco) 057331 Coil is a heavy-duty AMG120 solenoid coil engineered for high-performance HVAC and refrigeration applications. Operating at 120VAC 50/60 Hz with a 12-watt power rating, this Class F insulated coil is built to withstand standard temperature variances while maintaining consistent magnetic force for valve actuation. This specific model features an integrated junction box with 6-inch leads and dual knockouts, simplifying field wiring for contractors. It is a direct OEM replacement for AHG120 and 200537A models, ensuring seamless integration into existing systems. Primarily used as an unloader coil for Copeland and Carlyle compressors, it is also rated for steam applications and a variety of solenoid-controlled refrigeration equipment. Its rugged construction minimizes electrical failure risks in demanding environments, providing the reliability required for commercial infrastructure.

Key Benefits:

• Broad Compatibility: Serves as a direct replacement for Alco 057331, AMG120, and AHG120 series coils.
• Simplified Installation: The integrated junction box and 6" leads allow for rapid HVAC solenoid repair without additional mounting hardware.
• Specialized Performance: Specifically designed to function as an unloader solenoid coil, critical for compressor capacity control.
• Industrial Grade Insulation: Class F coil insulation ensures thermal stability during continuous duty cycles.

Common Questions:

Can this coil be used on different voltage systems?
No, the AMG120/50-60 is strictly rated for 120V AC systems. Using this on 24V or 240V circuits will lead to immediate electrical failure or fire hazard.

Is this compatible with both refrigeration and steam valves?
Yes, the Alco solenoid coil 057331 is designed for versatility and is fully compatible with steam applications and standard refrigeration solenoid valves requiring a 12-watt pull.

What is the difference between the AMG and AHG series?
The AMG series, like the 057331 coil, typically replaces the older AHG series, offering improved junction box access and modern insulation standards while maintaining the same physical footprint.
