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 Spring-loaded terminal SIRIUS 3RP20 time relay, delayed response, for various time-delayed switching operations in control, starting, protection and regulating circuits, e.g. cascaded motor starting. 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 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.
