It is rated for 5.5 kW at 400 V in AC-2 duty — the category covering slip-ring motor starting and plugging — so the AC-2 figure is the one that governs the real motor load, not a higher AC-1 resistive number. The 45 mm width and 57.5 mm height let it sit on a 35 mm DIN rail per EN 50022, with screw and snap-on mounting that keeps panel layout dense.
Ratings and deployment context
Rated operational voltage covers 220 V at 50 Hz and 240 V at 60 Hz, with a permissible voltage tolerance of 0.85 to 1.1 times rated at 50 Hz and 0.8 to 1.1 at 60 Hz. Front protection is IP20, so the contactor itself is finger-safe once installed inside a panel with a higher-rated enclosure.
The wire cross-section range is 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and a maximum of 2x (0.75 to 4 mm²) — or 2x (20 to 16 AWG), 2x (18 to 14 AWG), and 1x 12 AWG. This covers most panel wiring from control-circuit signal lines up to motor power conductors. The depth of 72 mm is a standard dimension for Size S00 contactors, so it fits existing DIN-rail layouts without extra clearance.
