Emerson Alco 057342 Coil

The Emerson Alco 057342 Coil, also known as the AMG 208-240/60, is a high-performance solenoid valve coil designed for rigorous HVACR applications. This 208-240Vac 60Hz coil is rated at 12 watts and features Class F insulation, ensuring stable thermal performance and reliability in high-temperature environments. Built with an integrated junction box and 6-inch leads, this Type AMG coil simplifies field installation and wiring. It is engineered specifically for compatibility with Alco solenoid valves, providing the necessary inductive force to ensure clean plunger actuation and tight shut-off. For technicians servicing refrigeration racks or commercial AC units, this replacement solenoid coil offers the exact electrical specifications required to maintain system factory standards. The AMG series coil is a standard-tier component for contractors who prioritize HVACR system compatibility and long-term electrical durability without the risk of coil burnout due to poor insulation or fluctuating voltage.

Key Technical Benefits

• Class F Insulation Rating: Designed to withstand higher operating temperatures, preventing premature thermal breakdown during continuous duty cycles.
• Integrated Junction Box: Provides a secure housing for electrical connections, protecting 6-inch wire leads from environmental debris and mechanical strain.
• Optimized Power Consumption: The 12-watt power rating ensures efficient valve operation while minimizing auxiliary heat load on the solenoid assembly.
• Precise Voltage Tolerance: Engineered for 208-240Vac 60Hz systems, reducing the risk of hum or chatter in variable power conditions.
• Direct Fit Replacement: Maintains the OEM specifications for Emerson Alco hardware, ensuring seamless mechanical mounting on the valve stem.

Common Questions

Can I use this AMG coil on a 50Hz electrical system?
This specific model is optimized for 60Hz operation. Running a 60Hz coil on a 50Hz supply can lead to increased amperage draw and potential overheating. Always match the nameplate frequency for safe operation.

Is the junction box required for installation?
The junction box on the Emerson 057342 is integrated to meet specific electrical codes for field wiring protection. It is recommended for all commercial installations to ensure a moisture-resistant and secure connection.

How do I verify if this coil is shot?
Use a multimeter to check for continuity and resistance across the leads. An open circuit or a reading significantly outside of the manufacturer’s specified ohms generally indicates a burned-out solenoid coil that requires immediate replacement.
