It mounts via screw 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° tilt forward/backward. Depth is 73 mm, width 45 mm, height 70 mm.
Duty Cycle and Mechanical Life
Rated for 1,000 operating cycles per hour at AC-1 (resistive load), 750 ops/h at AC-2 and AC-3 (motor starting and running), and 250 ops/h at AC-4 (plugging/inching). The AC-3e rating also sits at 750 ops/h. Mechanical life is typical 30,000,000 operations. The auxiliary switch is included.
Terminal and Conductor Specifications
Spring-type terminals accept solid or stranded conductors from 0.5 to 4 mm², and can take two conductors of the same cross-section (2x 0.5...4 mm²). The main contact rating is 20...12 A (presumably the thermal current range).
