This product is part of the NEMA Pressure Switches range, an offer of water pump switches. This water pump switch has 2 normally open, snap action, DPST-DB (double pole single throw, double break) form XX contacts and a pressure setting value of 40psi to 20psi. The pump switch with a pressure sensor size of 65psi (23psi to 65psi), an adjustable range on rising pressure of 8psi to 45psi and approximate adjustable differential of 15psi to 30psi. It is furnished with screw clamp terminals for electrical connection and 0.25inch NPSF internal for fluid connection. This reverse action 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 3.1inch (W) x 3.76inch (D) x 2.8inch (H) and weighs 1lb. It is suitable for pressure controlling or monitoring of water pumps, compressors, agricultural/irrigation water systems, molding presses, injection molders, grinding machines, machining centers, complex and special machines. It is an IP20 and NEMA 1 rated product. This product is certified by CE, CSA and UL. Meets NSF ANSI 61 Annex G standards. The type FRG is reverse acting, the contacts open on falling pressure. Every pressure switch has two operating points, one on rising pressure and one of falling pressure. Power pressure switch rated for the direct control of motors in pump 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-user applications. The type FRG is reverse acting, the contacts open on falling pressure.
