This is a high - performance pressure switch. It has a maximum test pressure of 25 bar (363 psig), and a maximum operating pressure of 22 bar (320 psig). The enclosure protection level is IP54, which can effectively prevent dust and water splashing, ensuring reliable operation in various environments. The fluid group is 1. The burst pressure is 88 bar, indicating strong pressure - resistance performance. The ambient temperature range is from - 40 °C (- 40 °F) to 70 °C (158 °F), making it suitable for a wide range of working temperatures. In terms of electrical specifications, it complies with EN 60947 - 4/-5. The electrical connection is in the form of cable thread connection, with a size of 2xPg 13.5 and a female - threaded connection form, following the DIN 40430 standard. The contact function is SPDT. The contact capacity is AC15 = 3 A, 400 V; AC1 = 10 A, 400 V; AC3 = 4 A, 400 V; DC13 = 12 W, 220 V; LR = 28 A, 400 V. The adjustment range of pressure is from 1 bar (14.5 psig) to 10 bar (145 psig), which can meet different pressure - control requirements. The hysteresis is 0.6 bar (8.7 psi), ensuring stable operation. The pressure connection type is G, with a connection size of 1/2 and in accordance with the ISO 228 - 1 standard. The pressure connection is externally threaded, and the pressure - sensing element is a bellows. The contact system is repairable.
