Time relay, electronically delayed response 1 changeover contact AC/DC 24 V, AC 200 to 240 V at AC 50/60 Hz 0.05 s to 100 h Width 45 mm Screw connection Time relay SIRIUS 3RP20, delayed response, for various time-delayed switching operations in control, starting, protection and regulating circuits, e.g. cascaded motor starting. Wide application range thanks to diverse functions in the smallest of spaces. Can be used worldwide thanks to international approvals and wide voltage range. The 3RP time relays are available as single or multi-function time relays with semiconductor output or as electromechanical relays with and without positive guidance, each with different connection technologies. SIRIUS relays - a program for all cases.
