Description
The Trane CNT01045 Hi Limit Switch is a safety control component used to protect equipment from excessive temperature conditions by interrupting operation when heat levels exceed safe limits. It works through a temperature sensitive sensing element that opens the electrical circuit at a preset high temperature and automatically resets once the system cools back down. It is installed on or near the heat exchanger or airflow path where temperature monitoring is essential for safe operation. By preventing overheating, it supports protecting internals from damage, improves safety reduces system failures, and ensures stable performance in HVAC systems.
