Description
Trane SWT3277 High Pressure Switch is a safety essentialpart used in HVAC systems to monitor high pressure when is exceeded. It is a 6” long switch with an SPST contact arrangement that is used for sensing and switching high-pressure conditions in the system. It starts working at 650 PSI and stops working at 500 PSI, thus ensuring that overpressure is well protected against. The switch has an 8.0 FLA/48 LRA at 120/240 VAC, 375 VA pilot duty at 120/277 VAC, 125 VA pilot duty at 24 VAC, and 2A at 28 VDC. This small high-pressure switch helps to avoid damaging the system due to high pressure and increases the durability of HVAC equipment.
