It breaks fault currents up to 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No. 235, so it coordinates with standard panelboard bus ratings in both IEC and North American installations. The D curve (10–20× In) handles high inrush loads — motor starters, small transformers, solenoid banks — without nuisance tripping on startup.
The 5SY6213-8CC occupies 2 width units (36 mm) on a DIN rail, with a depth of 76 mm and height of 90 mm. It snaps onto the quick-assembly mounting system and accepts conductors at both top and bottom combined terminals.
It operates from -40 °C to 75 °C, with humidity derating above 55 °C (95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C). Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — enough for machine-mounted panels on pumps or compressors.
