Description
The Trane SWT3740 Pressure Switch is a small safety device that is an essential part of an HVAC system. This Switch is different than basic on/off switches, as it specifically monitors air pressure to make sure that it operates safely and efficiently. Two sets of terminals are normally open or normally closed which offers added versatility. The Trane has a pressure rating of -0.5″ of water column and will automatically respond when air pressure drops below a safe threshold. Trane operates at a standard voltage of 277V and makes sure your Trane HVAC system works safely and efficiently.
