The 45 mm width and 97 mm depth fit a standard 35 mm DIN rail (DIN EN 60715) with screw and snap-on mounting, so it occupies one 45 mm module in a panel. The AC-3 switching frequency of 750 operations per hour (maximum) and AC-4 at 250 ops/h define the duty cycle for motor starting and plugging. The auxiliary switch is included in the package — no separate order for a side-mount block on this variant. Main contact wire range accepts solid or stranded 1 to 10 mm², and the coil terminals accept 2x (0.5 to 2.5 mm²) solid or stranded, so the kit is complete for a standard motor starter build.
Mounting position is standing on a horizontal surface. The 10 million typical mechanical cycles give a long service life for conveyor or pump duty.
