This product is part of the NEMA Pressure Switches range, an offer of air compressor switches. This air compressor switch has 2 normally closed, snap action, DPST-DB (double pole single throw, double break) form YY contacts and off at 100psi pressure setting value. The pressure switch with a pressure sensor size of 100psi, an adjustable range on rising pressure of 40psi to 100psi and approximate fixed differential of 20psi. It is furnished with screw clamp terminals for electrical connection and 0.25inch NPSF internal for fluid connection. This high HP switch has a diaphragm actuator which can be operated from any position and fixed differential scale for internal settings. The enclosure is made of polypropylene. It is available in size of 2.78inch (W) x 3.76inch (D) x 3.71inch (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 UL 508 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 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-user applications.
