Eaton Cutler-Hammer C25DNY162T Contactor

The Eaton Cutler-Hammer C25DNY162T Contactor is a heavy-duty 3-pole definite purpose contactor engineered for the rigorous demands of the HVACR industry. Designed as a 50mm frame unit, this 40-amp contactor provides reliable motor control and protection for compressors, pumps, and heating elements. Operating on a 24VAC control coil (50/60 Hz), it ensures seamless integration with standard low-voltage residential and commercial thermostat circuits. The C25DNY162T is built for longevity in high-cycle applications, featuring a robust open enclosure design and high-quality silver cadmium oxide contacts to minimize electrical arcing and heat buildup. As a veteran in the field, you will appreciate its universal mounting footprint, which matches standard industry patterns for fast field replacements. Whether you are servicing a rooftop unit or a large chiller system, this direct-on-line (DOL) switching device delivers stable performance under inductive loads, maintaining the integrity of the electrical assembly without premature fatigue.

• High Amperage Capacity: Rated for a 40A inductive load, making it suitable for high-demand HVACR motors.
• Low Voltage Control: The 24V AC coil allows for easy synchronization with most HVAC control boards and 24-volt transformers.
• 3-Pole Configuration: Provides complete circuit isolation for three-phase equipment or multi-circuit control.
• Compact 50mm Footprint: Fits into tight control panels and standard NEMA enclosures commonly found in commercial units.
• Durable Construction: Engineered to withstand the thermal stresses and rapid cycling typical in refrigeration and air conditioning environments.

What is the maximum current rating for this contactor?
The C25DNY162T is specifically rated for 40 Amps at inductive loads, ensuring it can handle high-torque motor starts without contact welding.

Can I use this for both 50Hz and 60Hz systems?
Yes, the 24VAC coil is designed for dual-frequency operation, making it compatible with both 50Hz and 60Hz power supplies without sacrificing performance.

Is this a direct replacement for other 40A 3-pole contactors?
While it follows standard sizing, always verify the 50mm frame size and mounting holes; however, Eaton’s C25 series is the industry standard for definite purpose contactors in most OEM systems.
