Eaton Cutler-Hammer C25DNJ250T Contactor

The Eaton Cutler-Hammer C25DNJ250T is a heavy-duty 2-pole definite purpose contactor engineered for demanding HVACR and industrial motor control applications. This 50-amp non-reversing contactor features a 24VAC 50/60Hz coil and an open-type enclosure, making it a standard replacement for high-draw equipment including large condensing units and resistive heating loads. The C25DNJ250T utilizes a metal mounting plate for a rigid installation and is built with high-grade silver cadmium oxide contacts to ensure longevity under high-inrush conditions. This DP contactor is designed for easy integration with standard box lugs and quick connect terminals, facilitating fast field wire-ins. When replacing NEMA rated contactors or older Cutler-Hammer C25 series models, confirm that the FLA (Full Load Amps) and LRA (Locked Rotor Amps) ratings align with the compressor or motor nameplate requirements to prevent premature coil failure or contact welding.

• High Amperage Capacity: Rated for 50A Inductive and 65A Resistive loads, providing robust power handling for commercial HVAC systems.
• Standardized Footprint: The metal mounting plate features industry-standard hole patterns for a direct drop-in replacement.
• Optimized Coil Performance: The 24V coil is designed to operate efficiently within 50/60Hz frequency ranges to minimize chatter and hum.
• Durable Construction: Engineered with open frame architecture for better heat dissipation during continuous operation cycles.

Can the C25DNJ250T replace a 40-amp contactor?
Yes, you can substitute a 50-amp contactor for a 40-amp unit as long as the coil voltage (24VAC) and pole count match. The higher amperage rating provides a greater safety margin for the load.

What is the difference between a 2-pole and a 1-pole with shunt contactor?
A 2-pole contactor like the Eaton C25DNJ250T breaks both power legs of a single-phase circuit, whereas a 1-pole with shunt leaves one leg permanently energized. Always verify local codes before switching types.

Are the terminal lugs compatible with aluminum wiring?
These box lugs are typically rated for copper wire only. If utilizing aluminum, ensure you are using proper transition terminals and anti-oxidation paste to maintain electrical integrity.
