Time relay, electronic with star-delta function 1S delayed 1S undelayed 1 time range, 1...20 s AC 200-240 V and AC 380-440 V screw connection Time relay SIRIUS 3RP25, star-delta function, for the targeted starting of motors in star-delta circuits. Wide range of applications thanks to a variety of functions in the smallest of spaces. Can be used worldwide thanks to international approvals and a wide voltage range. The innovative housing concept in industrial design offers labeled cover flaps, removable connection terminals and much more. Available as a single or multi-function time relay with semiconductor output or as an electromechanical relay with and without positive guidance, each with different connection technologies. The 3RP25 time relays replace the proven 3RP15 series. SIRIUS relays - a program for all cases.
