Trane CTR1720 Contactor

Trane CTR1720 Contactor

The Trane CTR1720 is a high-capacity, 3-pole contactor engineered for heavy-duty commercial and industrial HVAC equipment. Built to handle a 75 FLA (Full Load Amperage) rating at a 120V coil voltage, this inductive load switch is a critical component for managing power delivery to high-draw compressors and blower motors. This specific model features an integrated auxiliary contact, providing essential feedback logic for control circuits or status indication. Designed for high-cycle reliability in demanding environments, the Trane CTR1720 contactor ensures stable electrical connections across 50/60 Hz systems, preventing the premature pitting and welding of contacts often seen in lower-grade alternatives. For technicians performing OEM HVAC parts replacement, this genuine Trane component offers precise fitment for popular commercial rooftop units and large-scale split systems where high-amperage switching is required. Using an OEM Trane contactor maintains the original engineering specifications of the system, supporting optimal circuit integrity and longitudinal performance in the field.

Key Benefits
  • Heavy-duty 75 amp contactor capacity supports high-load HVAC compressor and motor applications.
  • 3-pole configuration with an auxiliary contact allows for sophisticated control circuit integration.
  • 120V coil compatibility ensures a direct match for standard commercial control voltages.
  • Designed for industrial resilience, resisting contact pitting and thermal stress under continuous operation.
  • Universal mounting plate with slotted and hex head terminals facilitates efficient field installation.
Common Questions

What are the symptoms of a failing Trane CTR1720 contactor?
Common indicators include burnt or "chattered" contacts that cause the compressor to hum without starting, visible pitting on the contact surfaces, or a continuous buzzing sound from the 120V coil. If the auxiliary contact fails, you may notice that secondary control logic or status lights are not operating despite the main poles being engaged.

Does this 75 amp contactor replace lower amperage models?
While a higher FLA rating can often handle the load of a smaller contactor, it is critical to verify the physical footprint and coil voltage. The Trane CTR1720 is specifically sized for 75A applications; always prioritize matching the OEM part number to ensure proper clearance within the electrical cabinet.

Can this contactor be used for lighting or motor control beyond HVAC?
Yes, its robust 3P design and 93A resistive rating make it highly effective for high-intensity lighting banks and industrial motor control circuits requiring a 120V control signal.
