Trane CTR2731 Contactor

Trane CTR2731 Contactor

The Trane CTR2731 is a commercial-grade 3-pole definite purpose contactor designed for high-demand HVACR applications requiring reliable switching of power circuits. Engineered with a 120V coil and a 40 amp inductive rating, this genuine OEM Trane part ensures seamless integration and prevents the premature component failure often associated with generic alternatives. This contactor features a three-pole configuration and double-pole power switching, providing the technical capacity to manage heavy electrical loads up to 600V in three-phase systems.

For field technicians, the CTR2731 (also referenced as CTR02731) is the standard for service replacements in Trane and American Standard rooftop units or chillers. Its magnetic contactor design includes screw terminals for secure lead connections and often incorporates an auxiliary contact for feedback loops or secondary control circuits. By utilizing this 40A DP contactor, contractors maintain the specific 50/60Hz frequency requirements and mechanical interlocking needed for safe, efficient system cycling.

Key Benefits for HVACR Systems

  • Optimized Load Management: Rated for 40 amps to handle high-current compressor and motor start-ups without contact pitting.
  • Broad Compatibility: Functions as a direct legacy replacement for Trane CTR2731 and CTR02731 part numbers.
  • Enhanced Durability: Built to OEM specifications, ensuring the silver cadmium oxide contacts resist welding under heavy three-phase loads.
  • Simplified Installation: Features standard mounting footprints and screw terminal configurations for fast field swaps.

Common Questions

Can I use a 24V coil contactor to replace the CTR2731?
No. The Trane CTR2731 requires a 120V control circuit. Using a different coil voltage will result in either a failure to pull in the contacts or immediate coil burnout.

Does this 3-pole contactor replace a 2-pole version?
While a 3-pole contactor can technically switch a 2-pole load, it is best practice to match the original 3P configuration to maintain proper phase separation and safety clearances within the control box.

What is the maximum voltage for the power contacts?
This definite purpose contactor is rated for power circuits up to 600VAC, making it suitable for standard 208V, 230V, and 460V three-phase HVAC equipment.
