Rated AC-3 ≤440 V 16 A, it handles reversing duty on a motor load up to that current; AC-3 is the motor-switching category per IEC 60947-4-1, so the 16 A figure is the real-world current for starting and stopping a squirrel-cage induction motor, not a resistive-heater rating. The coil is 440 V AC, matching a common control voltage in European 400 V three-phase panels. Operating temperature spans -25 to 50 °C, with storage from -50 to 80 °C; the 2000 m altitude rating without derating covers most industrial sites below that elevation.
This reversing contactor is sized for a control panel — the 90 mm width, 58 mm height, and 57 mm depth fit a standard DIN-rail footprint alongside other TeSys K components. The preassembled reversing busbar saves panel-build time: no separate interlock wiring, just land the motor leads and control coil. Mechanical robustness is specified for shock and vibration — 10 Gn on Y and Z axes with contactor closed, 4 Gn vibration closed at 5–300 Hz — so it holds in on mobile equipment or near rotating machinery. Flame retardance meets V1 per UL 94 and Requirement 2 per NF F 16-101/102, which matters for rail and transit applications where fire-smoke-toxicity compliance is mandatory. The protective treatment conforms to IEC 60068 and DIN 50016, covering corrosion resistance in humid or mildly aggressive atmospheres.
