Electronic timing relays are used in control, starting, and protective circuits for all switching operations involving time delays. Thanks to their compact design, the 3RP20/25 timing relays are the ideal timer modules for industrial manufacturers of control cabinets, switchgear and control systems. Due to the narrow design, the 7PV15 timing relays are ideal in particular for use in heating, ventilation and air-conditioning systems and in compressors.
