Rated AC-3 at 12 A up to 440 V, it handles reversing motor loads in that current band — think small conveyors, pump direction changes, or fan reversals where the mechanical interlock is built in. The 220...230 V AC coil matches standard control-voltage transformers common across industrial panels. IP20 finger-safe terminals keep the wiring zone protected inside the enclosure.
AC-3 at 12 A is the motor-switching rating — the one that governs real inductive loads. The 57 mm depth and 90 mm width fit a standard DIN-rail footprint. At 58 mm tall it leaves room above for a terminal block or overload relay in the same row. Operating altitude to 2000 m without derating covers most installations; above that you'd need to account for reduced air density on thermal dissipation. Ambient range -25 to 50 °C is typical for indoor panel environments.
Preassembled with the reversing power busbar means the mechanical interlock and main power connections are already aligned — no risk of cross-wiring the reversing pair. Just land the line and load sides, wire the coil, and commission. Flame retardance rated V1 per UL 94 and compliant with NF F 16-101/102 — relevant for rail or transport applications where fire-smoke-toxicity requirements apply. Shock and vibration ratings per IEC 60068-2-27 and -6: the contactor holds closed through 10 Gn on Y/Z axes and 15 Gn on X, so it stays engaged under moderate mechanical shock without nuisance dropout.
