Description
The Trane SWT3211 is a factory-engineered high-pressure switch designed to protect refrigeration circuits in Trane HVAC systems from damaging over-pressure conditions. With a precisely calibrated open setpoint of 650 PSI and a close setpoint of 500 PSI, this switch automatically interrupts the circuit when system pressure exceeds safe operating limits and resets once pressure returns to an acceptable level — helping prevent compressor damage and costly system failures.
Built to Trane’s exacting OEM specifications, the SWT3211 is a direct-fit replacement that ensures consistent, reliable performance in the field. Whether you’re servicing a commercial rooftop unit, a chiller, or another Trane refrigeration system, this switch delivers the pressure protection your equipment demands.
