Pressure Controls Series PS3 / Standard types Compact Pressure Switch with fixed switch-point settings Technical Data 110 Features • Maximum operating pressure up to 43 bar / test pressure up to 48 bar • Standard factory settings from stock in small volumes • High and low pressure switches • High temperature version with snubber for direct compressor mounting (range 6) • Direct mounting reduces the number of joints and thus avoiding potential leakage • Precise setting and repeatability • IP 65 protection if used with PS3-Nxx and PS3- Lxx cables with plug (acc. EN 175301-803), no additional gasket required (molded into plug) • Cables with plug to be ordered separately Standards • per Low Voltage Directive • per PED Directive 97/23 EG, TÜV appr. versions only • Manufactured and tested to standards on our own responsibility • Underwriter Laboratories Protection acc.
