Description
The Trane CNT03782 Limit Switch/Thermostat is a temperature control used to monitor heat levels in protected equipment circuits. It operates on a 200F trip point and uses an SPST normally closed configuration that opens when excessive temperature is detected, then resets automatically once conditions return to normal. It is commonly used in air handlers, packaged units, and furnace assemblies to monitor airflow and internal temperature rise within heating or cooling sections. The switch connects through wire leads into the control circuit and interrupts operation when limits are exceeded, maintaining controlled temperature conditions within HVAC systems during continuous cycling.
