It's a 3-pole unit rated AC-3 at 9 A up to 440 V, with a 230 V AC coil and one N.O. auxiliary contact.
The AC-3 rating of 9 A at 440 V is the motor-switching current — this contactor is sized for a 3-phase motor drawing up to 9 A under full-load starting conditions. AC-1 (resistive) and AC-4 (inching/plugging) ratings also apply, so it covers both simple on/off and reversing duty cycles. The 230 V AC coil draws from a control transformer or line voltage; verify coil suppression matches the PLC output if driven from a solid-state source. The 57 mm depth and 90 mm width fit standard DIN-rail enclosures, but the reversing busbar adds width — check fill factor against the gland plate before committing the panel layout.
Reversing contactors like this one are the standard building block for forward/reverse motor control in conveyors, hoists, pumps, and small machine tools. The preassembled reversing busbar saves panel wiring time compared to two separate contactors with an interlock kit.
