Description
The Trane CNT03786 SPST Limit Control is a temperature-sensitive safety switch to monitor internal heat conditions within equipment assemblies. Rated to open at 225F and reset automatically once temperatures return to the normal range, it operates as a normally closed (NC-1) SPST control within the safety circuit. This component is commonly applied in furnaces, air handlers, and other HVAC systems where temperature limits must be monitored during operation. It is positioned in the airflow or heat zone to transmit temperature-based signals to the control circuit for regulated equipment response.
