This product is a differential pressure switch, model RT262A. It has a maximum test pressure of 13 bar (188 psig) and a maximum working pressure of 11 bar (160 psig). The enclosure protection level is IP66. The environmental temperature range is from -50 °C (-58 °F) to 70 °C (158 °F). The electrical specifications comply with EN 60947 - 4/-5. The electrical connection is of cable thread type, with a size of 2xPg 13.5 and an internal thread connection form, following the DIN 40430 standard. The contact function is SPDT (non-snap action), and the contact capacity is 25 VA, 24 V AC/DC. The adjustment range of pressure is from -1 bar (-15 psig) to 10 bar (145 psig). Regarding the EN 60947 wiring properties, it supports flexible wires with ferrules (0.2 - 1.5 mm²), flexible wires without ferrules (0.2 - 2.5 mm²), and solid or stranded wires (0.2 - 2.5 mm²). The EN 60947 electrical properties include insulation of 400V, a pollution level of 3, a rated impulse voltage of 4 kV, and short - circuit protection with a 10A fuse. The pressure connection is of type G, with a size of 3/8 and a standard of ISO 228 - 1. The pressure connection has male threads, and it should be noted that a welding reducing pipe of 6.5/D10mm is required. The switch is repairable for the contact system, and its contact hysteresis is 0.03 bar.
