Its headline rating: AC-3 duty at ≤440 V, 9 A, with a 100 V DC coil. The 9 A figure at 440 V tells you the motor FLA it can handle; for a 400 V line, that typically covers a 3–4 kW motor, depending on the duty cycle. The contactor also carries AC-4 and AC-1 utilisation categories, so it can manage inching/plugging (AC-4) and resistive loads (AC-1) within its thermal current limits. The power circuit is rated for 690 V AC 50/60 Hz, giving headroom for 480 V or 575 V systems, though the AC-3 current rating derates above 440 V — check the thermal curve for higher voltages.
The contactor is IP20 rated (finger-safe terminals per VDE 0106), so it's intended for enclosure or panel mounting — not exposed washdown areas. The preassembled reversing busbar saves panel wiring time, but verify the busbar orientation matches your reversing starter layout before committing the panel. The coil is 100 V DC, so it needs a DC supply or a rectified AC source. The contactor includes one NC auxiliary contact (the '01' in the code), which is typically used for electrical interlocking in the reversing circuit — a standard practice to prevent both contactors from closing simultaneously.
