Time relay, electronically delayed response 1S (semiconductor) 2-wire 4 time ranges 0.05...240 s AC/DC 12-240 V screw connection Time relay SIRIUS 3RP25, delayed response, for various time-delayed switching operations in control, starting, protection and regulating circuits, e.g. cascaded motor start-up. Wide application range due to diverse functions in the smallest of spaces. Can be used worldwide thanks to international approvals and 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 Relay - a program for all cases.
