Description
The Schneider Electric (Square D) 9012GCW1 Pressure Switch is a control component constructed to measure, and control pressure in HVAC systems by opening and closing electrical contacts depending on the predetermined pressure levels. It operates on a piston-driven system which detects changes in pressure and opens an SPDT contact to operate equipment connected to it. It has a range of 20 to 1200 PSI, which is adjustable and an NEMA-4 enclosure that can be connected to piping and control wiring to operate properly. It is used to sustain pressure balance, system protection and effective control in varying pressure conditions.
