It's a 3-pole (3 NO main poles) contactor rated AC-3 at 6 A up to 440 V and AC-4 duty, with a 110 V AC coil and one NC auxiliary contact. The IP20 finger-safe enclosure (per VDE 0106) means it's suited for enclosed panel mounting where accidental contact is prevented.
The AC-3 rating of 6 A at <=440 V is the motor-switching current — it handles starting currents of small three-phase motors up to roughly 2.2 kW at 400 V. The 110 V AC coil is a common control voltage in older European panels; verify your control transformer matches before wiring. The NC auxiliary contact provides a feedback signal for the reversing interlock or status indication. Mechanical robustness specs show the contactor holds closed through 10 Gn shocks on Y and Z axes (15 Gn on X when closed) and 4 Gn vibration at 5–300 Hz — this is a rugged unit for industrial environments with moderate vibration, like conveyor lines or pump skids. Operating temperature range is -25 to 50 °C, storage from -50 to 80 °C, and altitude rating is 2000 m without derating. Flame retardance meets V1 per UL 94 and NF F 16-101/102, important for rail and transport applications. Protective treatment conforms to IEC 60068 and DIN 50016 for corrosion resistance.
At 57 mm deep, 90 mm wide, and 58 mm tall, this reversing contactor fits a compact footprint — about the size of two standard contactors side by side but pre-busbarred. The IP20 rating means it's intended for enclosure mounting where the front panel or door provides the next level of protection. Mounting is via the standard DIN rail clip or screw fixing; the preassembled power busbar reduces wiring errors on reversing applications like motor direction control.
