Eaton Cutler-Hammer 9-1891-1 Coil

The Eaton Cutler-Hammer 9-1891-1 Coil is a high-performance 120V replacement coil specifically engineered for heavy-duty industrial applications. Designed for seamless integration, this magnetic coil serves as a direct renewal part for NEMA Size 4 and NEMA Size 5 motor starters and contactors. It is fully compatible with 3 pole definite purpose contactors rated at 200A, 300A, and 360A, making it an essential component for maintaining high-amperage motor control systems. The encapsulated red cast resin construction ensures superior insulation and durability in demanding environments, while the 110/120Vac 50/60Hz dual-frequency rating provides versatility across different power supply standards.

For technicians servicing Eaton Freedom Series or Citation A1 and B1 models, the 9-1891-1 offers a 180mm frame size fit that ensures precise mechanical alignment. This Type A magnetic coil features a power rating of approximately 1,040 VA inrush, providing the necessary force to reliably actuate large-scale contactor assemblies. By utilizing this authentic renewal part, contractors can ensure their motor control centers maintain optimal electrical conductivity and thermal resistance without the risk of mismatching critical specifications.

• Precise Compatibility: Fits NEMA Size 4 and 5 starters and 200A–360A definite purpose contactors.
• Dual Frequency Operation: Supports both 110V/50Hz and 120V/60Hz systems for global application flexibility.
• Rugged Construction: Encapsulated in red cast resin to protect windings from moisture, dust, and vibration.
• High Power Capacity: Engineered with a 1,040 VA inrush rating to handle the demands of large 3-pole contactors.
