Eaton Cutler-Hammer 505C806G01 Coil

The Eaton Cutler-Hammer 505C806G01 Coil is an essential replacement component engineered for use with A200 and A201 series non-reversing and reversing starters. This 120VAC 60Hz replacement coil (110VAC 50Hz) is built specifically for NEMA Size 5 motor control centers and contactors. Designed to withstand high-duty cycles in demanding industrial environments, the 505C806G01 ensures reliable magnetic actuation for heavy-duty switching applications. When diagnosing field failures such as shorted turns or overheating, swapping the existing coil with a genuine Eaton A200 coil restores the electrical integrity of the starting circuit without the need for a full contactor replacement. This coil features encapsulated winding construction to resist moisture and mechanical vibration, maintaining consistent holding VA and inrush VA characteristics across the 120V control circuit.

• Direct Compatibility: Fits Eaton/Cutler-Hammer A200 and A201 Size 5 series assemblies.
• Industrial Build: Encapsulated design protects against insulation breakdown in high-heat environments.
• Field Efficiency: Direct drop-in replacement reduces downtime during maintenance windows.
• Voltage Stability: Rated for 120V 60Hz and 110V 50Hz, ensuring consistent pull-in and dropout voltages.

What is the primary cause of failure for an A200 Size 5 coil?
Most failures result from low control voltage causing chatter or excessive heat, leading to insulation breakdown. Always verify 120V at the coil terminals under load.

Can I use the 505C806G01 in a Size 4 contactor?
No, this coil is specifically sized for NEMA Size 5 frames. Cross-referencing the frame size is critical to ensure proper magnetic force and physical fit.

Does this coil include the magnet assembly?
This is the replacement coil only. If the magnet laminations are damaged or pitted, the entire assembly should be inspected for mechanical binding.
