Description
The Trane CNT01219 Temperature Control Limit Switch is a thermal sensing module used to monitor temperature levels within equipment assemblies. It operates as a single pole single throw (SPST) switch that opens the electrical circuit when temperatures reach 170F, sending a shutdown or control signal to the system. This component is commonly applied in furnaces, air handlers, and other HVAC systems where temperature limiting is required for controlled operation. It is positioned in the airflow or heat zone to detect rising temperatures and trigger circuit interruption during operating cycles.
