Description
The Trane® CNT3666 is an SPST pressure switch with a factory setpoint of 0.15 inches of water column (WC) for OEM HVAC replacement. It connects through a 1/4-inch barbed fitting and makes or breaks a single circuit as system pressure crosses the setpoint. Trane uses this switch to prove draft or airflow and protect the sequence of operation in furnaces and air handlers. Technicians install it as a direct-fit replacement to restore accurate pressure-proving in Trane equipment.$106.75
