Optimized Airflow: High 33-degree pitch allows for superior air movement in low-pressure condenser applications

Whether used for steam boiler safety or potable water level management

or threaded directly onto the rolled threads

Easy Installation: Includes 6-foot pigtail leads and a strap-on design that eliminates the need for thermal wells or system shutdowns

Trane CNT1662 High Limit Optimized Airflow: High 33-degree pitchThe Trane CNT1662 High Limit is a critical safety component designed for precise thermal regulation within furnace and air handler heat exchangers. Built with an L250F SPST NC C High limit configuration, this switch acts as a failsafe by monitoring supply plenum temperatures and interrupting the 24V control circuit if levels exceed the 250F threshold. This immediate shutdown of the gas valve helps prevent structural damage to the primary heat
