Trane CTR2576 Contactor

The Trane CTR2576 is a professional-grade 2-pole 40 amp contactor engineered for reliable motor and compressor switching in residential and light commercial HVACR systems. Operating with a 24V coil, this component serves as the direct replacement for CTR1155, as well as obsolete part numbers CTR01155, CTR01015, and CTR01075. Featuring heavy-duty screw terminals, it allows for secure ring terminal connections, ensuring a high-torque interface that prevents arcing and terminal burnout under 40A FLA loads. This OEM Trane contactor is designed to handle the inductive inrush of air conditioner compressors and fan motors, providing a definitive solution for chatter-prone or welded-pole scenarios. For technicians performing a HVAC contactor replacement, the CTR2576 offers the exact footprint and specifications required for Trane and American Standard condensing units, maintaining the electrical integrity of the control circuit and high-voltage power distribution.

• Direct OEM Compatibility: Specifically designed to replace the Trane CTR1155 and older iterations without mounting modifications.
• Enhanced Electrical Integrity: The 40 amp 2-pole configuration provides robust switching for high-demand inductive loads up to 600V.
• Secure Terminiation: Standard screw connections enable a professional-grade fit for existing ring terminals, reducing installation time in the field.
• Quiet Operation: Precision-wound 24VAC control coil prevents humming and ensures positive contact seating during heating and cooling cycles.

Will the Trane CTR2576 replace a 30 amp contactor?
Yes, this 40 amp contactor can safely replace a lower 30A rated component as it provides a higher current-carrying capacity, provided the 24V coil and physical dimensions align with the existing housing.

How do I know if my CTR2576 contactor has failed?
Technicians should check for continuity across the coil, pitted or welded contacts, and ensure the plunger is not mechanically seized. If the 24V signal is present but the load is not energized, a replacement is necessary.

Can I use this for both air conditioners and heat pumps?
Yes, this is a universal Trane replacement part for any 2-pole, 40A, 24V application within Trane and American Standard outdoor units.
