It is rated for AC-3 duty (motor switching) and covers a thermal protection adjustment range of 4...6.3 A, so it is sized for small three-phase induction motors in that current window.
The coordination type is Type 1, so after a fault the starter may need contact replacement, but the breaker and contactor are sized to clear the fault without upstream damage. Motor power ratings span 2.2 kW at 400/415 V up to 3 kW at 500 V, which maps to the 4...6.3 A thermal range in practice. The magnetic tripping current is fixed at 78 A — this is the instantaneous magnetic trip that clears a short-circuit or stall condition. It is not adjustable; the thermal adjustment range (4...6.3 A) is what you set for the motor's full-load current. The 45 mm width (3-module DIN footprint) and 152 mm height mean it occupies one standard DIN-rail position in the enclosure, with 87 mm depth behind the panel.
This is a reversing DOL starter — it handles forward/reverse control of a three-phase motor directly across the line, without a VFD. Typical loads are small conveyors, hoists, gate operators, or any application where the motor must run in both directions and the starting current inrush (typically 6-8x FLA for a standard induction motor) is acceptable. The reversing contactor pair is interlocked mechanically and electrically inside the assembly, so you do not need external interlocking relays.
