It mounts via screw fixing or snap-on onto 35 mm DIN rail per DIN EN 60715, with a mounting position that allows +/-180° rotation on a vertical surface and +/-22.5° forward/backward tilt. Dimensions of 140 mm height, 96 mm width, and 152 mm depth define the panel space required.
The AC coil is rated at 220 V at 50 Hz and 220 V at 60 Hz, with a coil operating range that covers standard European and North American control voltages. The screw-type coil terminals accept 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded wire. Main contact wire capacity accepts 6 to 70 mm² stranded conductors, sized for the S3 frame's current ratings. The arcing time is 10 to 20 ms AC, with shock resistance rated at 10.6 g for 5 ms and 6.3 g for 10 ms DC.
