It uses spring-loaded connection technology for the control circuit. This coil is a phased-out product. The manufacturer lists the successor as the SIRIUS 3RT2 series. The 400 V AC 50 Hz / 440 V 60 Hz rating means this coil is designed for standard European three-phase control voltages that vary slightly with line frequency. The 0.8 to 1.1 operating range at 50 Hz tells you the coil will pick up and hold reliably even if the control supply dips to 320 V or rises to 440 V — a practical margin for industrial panels where voltage sag from motor starting is common. It is a replacement coil, so the only fit question is whether your contactor is a SIRIUS Size S2; if it is, this coil drops in with spring-loaded terminals that accept solid or stranded wire without needing a screwdriver. ## Panel integration Snaps onto the SIRIUS Size S2 contactor body. The spring-loaded connection saves panel-builder time on the wire terminations — strip 8 mm, push the wire in, done. No separate mounting hardware needed beyond what the contactor already uses on the DIN rail.","metaTitle":"Siemens 3RT1934-5AR62 SIRIUS magnet coil, 400 V AC, 50/60 Hz","metaDescription":"Siemens SIRIUS 3RT1934-5AR62 magnet coil for Size S2 contactors, 400 V AC 50 Hz / 440 V 60 Hz.
