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

including gas-fired wall heaters and millivolt floor furnaces

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

Reliable Switching: Built to manage the arcing and heat generation typical of high-current switching in HVAC applications

Durable Construction: Heavy-duty housing and terminal pins designed to withstand high-vibration HVAC environments

Trane CNT1662 High Limit Easy Installation: Includes 6-foot pigtailThe 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
