It's rated for motor switching at 5.5 kW under AC-2 duty at 400 V — that's the standard contactor for moderate induction motor loads like pumps, fans, and small conveyors in a control panel. The S00 frame keeps the footprint compact at 45 mm wide, 57.5 mm tall, and 72 mm deep, so it fits in tight DIN-rail enclosures without hogging space. The front and terminal areas carry IP20 finger protection, so it's safe for open-panel installations behind a cabinet door.
The headline motor rating is 5.5 kW at AC-2 / 400 V — AC-2 covers wound-rotor motors and some slip-ring applications where the contactor makes and breaks load current at reduced speed. For across-the-line starting of standard squirrel-cage motors, AC-3 is the usual duty, and this contactor's AC-3 rating is typically higher than the AC-2 figure. The auxiliary contact block handles 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — those ratings cover pilot duty for PLC inputs, relay coils, and indicator lamps. The mechanical life is typical 30 million operations, so it'll outlast most machinery rebuild cycles.
Wiring and terminal details
Screw-type terminals on the main current circuit accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. That covers standard panel wire sizes from signal-level runs up to 4 mm² power feeds. For short-circuit protection, the recommended fuse is gL/gG 20 A with Type 2 coordination, or 35 A with Type 1 coordination — so you can match the fuse to your upstream breaker coordination study.
