9013GHG commercial or light industrial pressure switch is used to control electrically driven water pumps and air compressors. It has higher electrical ratings for direct control of motors in pump and compressor applications. 9013GHG pressure switches are diaphragm actuated. The contacts in these pressure switches open on rising pressure. 9013GHG pressure switches are UL Listed and CSA certified as commercial or light industrial control equipment. It is furnished with screw clamp terminals for electrical connection and 0.25inch NPSF internal for fluid connection. This switch has a diaphragm actuator which can be operated from any position and adjustable differential scale for internal settings. The enclosure is made of polypropylene. It is available in size of 3.44inch (W) x 3.88inch (D) x 5.4inch (H) and weighs 2.25lb. It is suitable for pressure controlling or monitoring of water pumps, compressors, agricultural/irrigation water systems, moulding presses, injection moulders, grinding machines, machining centres, complex and special machines. It is an IP20 and NEMA 1 rated product. This product is certified by CE, CSA and UL. Meets UL 508 and NSF ANSI 372 standards. Every pressure switch has two operating points, one on rising pressure and one of falling pressure. The operating point on rising pressure is referred to as the TRIP POINT or cut out for pumps and compressors. Power pressure switch rated for the direct control of motors in pump and compressor applications. Rugged, robust construction provides a long life and years of uninterrupted, worry-free service. Electromechanical switch to monitor and control pressure conditions for industrial and end-users applications.
