Trane CNT3511 Limit Switch 320819-301 Fail-safe operation: Reliable spring returnThe Trane CNT3511 is a commercial grade 120F CO Auto Limit Switch designed for precise thermal regulation and safety in high demand HVAC systems. As a single pole single throw (SPST) normally closed (N C) device, this component provides critical circuit interruption when internal plenum temperatures exceed the 120 degree Fahrenheit threshold. Engineered for automatic reset functionality, the CNT3511 eliminates the need for manual intervention once
