Emerson Alco 057540 Coil

The Emerson Alco 057540 Coil is a high-performance solenoid valve coil engineered for industrial and commercial refrigeration environments. Specifically designed as part of the Model AMF series, this 208-240Vac coil operates at 60 Hz with a 12-watt power draw, ensuring precise electromechanical actuation for refrigerant flow control. The open frame coil construction features 18-inch leads and Class F insulation, providing high thermal stability and resistance to the typical vibrations found in heavy-duty HVACR duty cycles. This replacement solenoid coil is an essential component for maintaining the integrity of 200RB, 240RA, and similar series solenoid valves by converting electrical input into the magnetic force required to seat or unseat the plunger effectively.

• Technical Reliability: The Class F insulation rating ensures the Emerson Alco 057540 maintains electrical integrity under high-temperature operating conditions common in condenser applications.
• Precise Actuation: Designed for an exact fit in Model AMF solenoid housings, ensuring consistent magnetic field strength for reliable valve cycling.
• Versatile Integration: The 18-inch lead length allows for flexible wiring within control panels or junction boxes without requiring additional splicing.
• Optimized Power Draw: 12-watt consumption provides the necessary pull-in and holding force for various refrigeration fluids without excessive heat generation.

Is the 057540 coil compatible with 50 Hz power supplies?
This specific model is rated for 60 Hz operation at 12 watts. For 50 Hz applications, while some AMF series coils are dual-rated (50/60 Hz), you should verify the specific voltage and frequency requirements of your system to prevent coil burnout.

Can I use this Model AMF coil to replace an ASC2 style coil?
The AMF is an open frame coil with leads, whereas the ASC2 often utilizes a DIN connector. While the internal bore may fit the same valve stem, the housing and electrical connection methods differ, so ensure your enclosure supports an open frame lead design.

What valves are compatible with the Emerson 057540?
It is commonly used with Emerson Alco 100RB, 200RB, 202CB, 211CA, and 240RA series solenoid valves. Always check the physical stem size and the "AMF" designation on the existing coil housing before installation.
