It carries 4 normally-open main contacts and is rated for 7.5 kW at 400 V in AC-2 duty, which covers slip-ring motor starting and plugging applications where the contactor makes and breaks the load current.
The S0 footprint — 71 mm wide, 85 mm tall, 150 mm deep — fits the common panel layout for this frame class. Front-side protection is IP20; the terminals themselves are IP00, meaning the wiring zone expects enclosure protection.
Main current circuit terminals are screw-type, accepting solid conductors from 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or up to 2x 4 mm². Finely stranded with core-end processing follows the same range.
