Trane CTR2738 Mechanical Interlock for Contactor
The Trane CTR2738 is a mechanical interlock designed for use with contactors in HVAC systems. This interlock provides a critical safety function by physically preventing two contactors from being engaged at the same time — a common requirement in reversing, transfer, or dual-contactor circuit configurations found in commercial and residential HVAC equipment.
Key Features
- Genuine Trane OEM replacement mechanical interlock
- Designed to prevent simultaneous energization of paired contactors
- Enhances electrical safety and protects downstream components
- Engineered for reliable, long-service-life performance in HVAC applications

Why Use a Mechanical Interlock?
In HVAC systems where two contactors control opposing functions — such as heating and cooling stages, or forward and reverse motor operation — a mechanical interlock is essential. It ensures that only one contactor can close at a time, preventing short circuits, equipment damage, and potential safety hazards. The Trane CTR2738 delivers this protection as a factory-engineered component built to Trane’s exacting standards.
Application
