This is the Danfoss KPS47 pressure switch, belonging to the Switches and thermostats product series. It comes with relevant switch accessories and is packaged in multiple - unit packs. Pressure - related Parameters The adjustment range of the pressure switch is Pe 6 - 60bar (87 - 870psig), and the hysteresis range is 3.5 - 17bar (51 - 247psi). It has an automatic reset function, which is convenient for continuous operation. The pressure connection type is G, with a size of 1/4 and complies with the ISO 228 - 1 standard. The maximum working pressure is 120bar (1740psig), the maximum test pressure is 180bar (2611psig), and the burst pressure is 240bar. The pressure - sensing element is a diaphragm, and the pressure connection is internally threaded. Electrical - related Parameters For electrical connection, it uses a cable thread connection with a size of Pg 13.5 and an internal - threaded form. It features a metal cable gland and adheres to the DIN 40430 standard. The contact function is SPDT with gold - plated contacts, providing excellent conductivity and durability. The contact ratings are as follows: AC15 = 4A, 440V; AC1 = 10A, 440V; AC3 = 6A, 440V; DC13 = 12W, 220V; LR up to 50A; for gold - contacts, 1…30mA, 5...30V. According to EN 60947, the wiring properties support flexible wires with ferrules from 0.5 - 1.5mm², flexible wires without ferrules from 0.7 - 2.5mm², and solid / stranded wires from 0.75 - 2.5mm². The electrical properties include an insulation rating of 400V, a pollution degree of 3, a rated impulse voltage of 4kV, and a short - circuit protection fuse of 16A. This pressure switch is a reliable choice for various industrial and control applications that require accurate pressure monitoring and switching.
