Eaton Cutler-Hammer C25CNB130T Contactor

The Eaton Cutler-Hammer C25CNB130T is a professional-grade definite purpose contactor engineered for heavy-duty cycling in HVAC, refrigeration, and industrial motor control. This single-pole with shunt model belongs to the C25 compact frame series, offering a space-saving footprint without sacrificing switching capacity. Techs and contractors rely on this unit for its 30A inductive full load rating and 40A resistive capacity, making it a standard replacement for residential and light commercial condenser units. The integrated 24VAC 50/60Hz coil ensures compatibility with common low-voltage control circuits, while the non-reversing design provides stable, long-term operation for compressor and fan motor loads.

Installation efficiency is maximized via the binding head screw and quick-connect terminals, allowing for versatile wiring field-side. The open type enclosure is built on a durable metal mounting plate for rigid attachment within narrow control cabinets. Compliance with UL recognition and CSA certification ensures this contactor meets rigorous safety standards for commercial deployments. For those managing tight service schedules, the C25CNB130T is the definitive choice for a 30 amp 1 pole contactor that maintains silver cadmium oxide contacts for arc resistance and longevity.

Key Benefits for HVACR Technicians

• High Durability: Features an inductive load rating of 30A and a 40A resistive rating for robust electrical performance.
• Efficient Wiring: Equipped with dual quick-connect and binding screw terminals to streamline field installation.
• Robust Construction: Designed with a metal mounting plate and an open frame for superior heat dissipation.
• Standard Certification: UL Recognized and CSA Certified to ensure industry-standard safety and reliability.

Common Questions

Can I use the C25CNB130T to replace a standard 1-pole contactor without a shunt?
Yes, the single pole with shunt design allows you to maintain a continuous path for the neutral or second leg of power while switching the primary leg, which is a standard configuration in many condensing units.

What is the difference between the FLA and LRA ratings for this model?
The C25CNB130T is rated for 30 Amps Full Load Amps (FLA) and has a Locked Rotor Amps (LRA) rating of 150A at 240V and 120A at 480V, ensuring it can handle the initial start-up surge of high-efficiency compressors.

Is the coil voltage strictly 24VAC?
This model is specifically designed for 24VAC 50/60Hz control circuits. Applying higher voltage to the coil terminals will result in immediate component failure.
