Trane CTR2729 Contactor

The Trane CTR2729 Contactor (also identified as the CTR02729) is a heavy-duty, field-proven 3-pole 60 amp 120V contactor engineered for the rigorous demands of commercial HVAC and industrial motor control. Built with silver-cadmium oxide contacts, this DP contactor delivers superior conductivity and prevents contact welding under high-locked rotor amp (LRA) conditions. For technicians, the definite purpose contactor design ensures a clean break across all three phases, making it an essential component for protecting large compressors and fan motors from electrical arcing. This Trane replacement part maintains a compact footprint while supporting up to 600V AC, allowing for seamless integration into existing control panels without extensive rewiring. Whether you are performing a preventative maintenance swap or a reactive repair, this OEM-spec HVAC contactor provides the physical durability and 120V coil responsiveness necessary to ensure system uptime and reliable power switching in critical environments.

• High-Capacity Switching: Rated for up to 60 amps, making it suitable for large-scale inductive loads and heavy-duty motor starts.
• Durable Contact Surfaces: Utilizes silver-cadmium oxide to minimize pitting and carbon buildup, extending the service life in high-cycle applications.
• 3-Pole Configuration: Provides simultaneous control over three power lines, ensuring synchronized operation for three-phase equipment.
• Standard 120V Coil: Compatible with most standard commercial control voltage circuits for simplified installation.

Common Questions
