AC-3 at 12 A is the motor-switching rating — it's what governs the contactor's ability to make and break locked-rotor current. That 12 A at 440 V covers a 5.5 kW (7.5 HP) motor at 400 V three-phase. The AC-4 rating covers plugging and inching duty, which is lower; if you're reversing under load frequently, derate accordingly. The preassembled reversing busbar saves panel-build time — the mechanical interlock and power bus are already integrated, so you wire the line and load sides directly. The 57 mm depth and 90 mm width mean it fits standard 45 mm DIN-rail spacing with room for adjacent devices. Operating altitude is 2000 m without derating. Above that, you'll need to account for reduced air density on the arc extinction and thermal dissipation.
