Allen Bradley 80153-576-51-R Electrically Held Closing Coil

Product Overview

The Allen Bradley 80153-576-51-R functions as a high-performance closing coil designed for large-scale industrial contactors and motor starters. This electrically held solenoid generates the necessary electromagnetic force to pull in the main contacts and maintain the circuit in the closed position during operation. Although the manufacturer has discontinued this series, we offer this unit as 100% Brand New and Factory Original, providing a critical replacement part to keep your legacy power distribution systems fully operational.

Technical Specifications

Engineering Advantages

• Precision Holding Power: The 80153-576-51-R delivers a consistent electromagnetic field that secures the contactor armature firmly. This high-integrity holding force eliminates contact "chatter" and prevents overheating or welding of the primary power tips during voltage fluctuations.

• High-Grade Copper Windings: The coil utilizes premium-grade, temperature-resistant copper wire. This robust construction prevents internal short-circuits caused by thermal expansion during continuous-duty cycles in congested control cabinets.

• Seamless Legacy Integration: This coil matches the exact mechanical footprint of the original 120V AC closing mechanisms. It allows maintenance teams to perform a direct drop-in replacement without modifying the contactor chassis or the secondary control wiring.

• Electrically Held Architecture: This design ensures the contactor automatically drops out during a loss of control power, providing an inherent fail-safe mechanism for motor protection and industrial safety protocols.

• Industrial Thermal Resilience: The encapsulation material resists the degrading effects of industrial lubricants and high ambient temperatures. This ensures the 80153-576-51-R maintains its dielectric strength over years of service in harsh manufacturing environments.

FAQs

• Can I use the 80153-576-51-R in a 110V AC application?

  The coil carries a 120V AC rating. While standard industrial control transformers often provide 110-120V, you must ensure the voltage remains within the OEM tolerance range (+10% / -15%). Operating consistently at significantly lower voltages may prevent the armature from seating fully, leading to coil burnout.

• How do I confirm this coil fits my specific contactor?

  Verify the part number on the side of your existing coil or check the contactor nameplate for compatible coil series. As a Brand New Original part, the 80153-576-51-R replaces identical legacy coils used in Allen Bradley high-ampere contactor frames.

• What are the primary indicators that the closing coil requires replacement?

  Watch for symptoms such as a distinct humming sound (indicating an unseated armature), visible discoloration of the coil jacket, or the contactor failing to pull in despite receiving 120V AC at the control terminals.

• Is this a refurbished or rewound component?

  Absolutely not. We guarantee this product is 100% Brand New and arrives in its original factory packaging. We do not sell rewound or used coils, as they lack the precise electrical impedance and reliability required for heavy-duty power control.
