Description
The Trane CNT01220 SPST Auto Limit Temperature Control Switch 160F is a normally closed thermal safety component used in heating systems to monitor and regulate internal equipment temperatures. It operates as automatic reset control that opens the electrical circuit when temperatures supports to avoid overheating conditions in HVAC systems. It is installed on heat exchangers, furnaces, or blower assemblies where it protects system components by interrupting operation during excessive heat buildup. The switch automatically resets once temperatures return to safe levels, supporting continued safe and controlled heating system operation.
