Rated AC-3 <=440 V 6 A, it switches three-phase squirrel-cage motors up to that current in reversing duty. The 440 V AC coil matches standard European control voltages. AC-3 is the utilisation category for starting and stopping squirrel-cage motors under load — the 6 A rating at <=440 V is the current the contactor can break reliably during normal motor starts. AC-4 (also listed) covers inching and plugging, where the contactor interrupts locked-rotor current, so this part handles both reversing and jogging cycles without derating.
IP20 finger-safe terminals suit enclosed panel mounting, not open washdown areas. Preassembled with reversing power busbar means no separate busbar kit to order and no risk of wiring the interlock wrong in the field. The 1 NC auxiliary contact provides a positive feedback path for the control logic to confirm the contactor state.
