Trane CTR1794 Contactor
The Trane CTR1794 is a robust 3-pole definite purpose contactor designed for high-cycle reliability in commercial and residential HVACR systems. Engineering specifications confirm a 24V coil voltage and a 25 Amp inductive rating, making it a standard replacement for Trane and American Standard air handlers and heat pumps. This general purpose contactor features 3-pole switching to manage three-phase power loads effectively while ensuring minimal contact bounce. Built for durability in demanding environments, the CTR1794 contactor handles locked rotor amps (LRA) significantly higher than its continuous rating, providing a necessary buffer during compressor startup. When replacing a burnt contactor, ensure the 24-volt control circuit is stable. This OEM Trane part ensures dimensional compatibility and correct terminal positioning for fast field installation, maintaining the efficiency of the condensing unit electrical system without requiring modifications to the existing wiring harness.
Key Benefits for the Technician- Industrial Grade Silver Cadmium Oxide Contacts: Resists welding and pitting under high-amperage startup loads.
- Standardized Mounting: Universal mounting base matches existing Trane HVAC contactor footprints for direct swap-outs.
- Encapsulated Coil: Protects internal windings from moisture and debris, reducing the risk of short-circuits.
- Triple Pole Configuration: Provides simultaneous switching of all three power legs for balanced phase loading.
What is the maximum FLA rating for this contactor?
The Trane CTR1794 is rated for 25 Amps Full Load Amps (FLA) and is typically used in systems requiring reliable switching for compressors and motors up to 30 Amps Resistive.
Can I use a 120V coil contactor to replace the CTR1794?
No. This unit requires a 24V AC control signal. Using a different coil voltage will result in component failure or a non-functional control circuit.
Is this contactor compatible with American Standard equipment?
Yes, as an OEM component for the Trane family, this 25A 3-pole contactor is the correct specification for compatible American Standard residential and light commercial units.
