Trane CNT4960 72" Hi Pressure Control Open 650 PSI Close 550 PSI

The Trane CNT4960 is a high pressure control safety switch used in Trane HVAC systems. Measuring only 1” high, 5.5” long, and 5.5” wide, this compact device is essentialin protecting the system from possible damage due to pressure build-up. It is designed with a pre-set operation range and is rated for a burst pressure of 140 psi. If the system pressure goes up to 650 psi, this shuts off the system to avoid further mishaps. When the pressure goes below 550 psi close pressure the control resets and the system is free to continue. The Trane is built durably with water-resistant housing (IP65) and can operate in a wide range of temperatures (-22°F to 185°F).
