Copeland Comfort Control (Alco) 057603 Coil

The Copeland Comfort Control (Alco) 057603 is a high-performance AMS Series solenoid coil engineered for precise fluid control in commercial refrigeration and HVAC systems. As a 24V AC solenoid coil, this component is designed to operate on 50/60 Hz frequencies, drawing 12 watts to provide the electromagnetic force necessary for reliable valve actuation. The Class F insulation rating ensures the winding remains stable under high thermal loads, making it a standard choice for Alco solenoid valve replacement in demanding environments.

Featuring integrated spade terminals, the 057603 coil allows for rapid field installation and secure electrical termination. This 12W HVAC coil is compatible with a wide range of Emerson and Alco valve bodies, including the 100RB and 200RB series (specifically models requiring the X-27979-S configuration). For technicians prioritizing system uptime, this 24-volt 12-watt coil offers the mechanical integrity needed to handle consistent cycling without overheating or performance degradation.

• Universal Compatibility: Specifically designed for Alco AMS Series valve bodies and various Copeland refrigeration parts.
• Thermal Resilience: Class F insulation protects internal windings against breakdown from ambient heat and electrical stress.
• Dual Frequency Support: Operates seamlessly on both 50Hz and 60Hz systems, providing flexibility for different power configurations.
• Streamlined Installation: Spade terminal connections simplify wiring for quick service calls and OEM assembly.
• Consistent Actuation: Provides 12 watts of power to ensure solenoid valve plungers seat and unseat reliably under full system pressure.

Is this coil compatible with DC systems?
No, the 057603 is specifically designed for 24VAC power supplies. Using this coil on a DC circuit will lead to immediate failure or improper valve operation.

Does this include the valve body?
This is a replacement solenoid coil only. The valve body and internal plunger assembly are sold separately.

What causes these coils to burn out?
Burnout often results from incorrect supply voltage, moisture ingress at the spade terminals, or debris holding the valve plunger open, which causes the coil to draw excessive current.
