Trane CNT3719 Control 322838-752 Quiet Operation: The scroll designThe Trane CNT3719 is a heavy duty, single pole single throw (SPST) low pressure control switch engineered to protect the compressor from low suction conditions and avoid thermal overloads. As a critical safety component in Trane HVAC systems, this switch monitors refrigerant levels and opens the circuit when pressure drops to 8 PSI, then automatically closes (resets) when pressure returns to 25 PSI. Built with a rugged IP65 rated casing, the CNT3719
