The C tripping characteristic (5–10× In) handles motor inrush and capacitive loads without nuisance trips, while the 4.5 kA breaking capacity per EN 60898 and IEC 60947-2 covers the typical prospective short-circuit current at the distribution board in a TN or TT system.
Derating and mounting
At 30 °C ambient the unit carries the full 32 A; derate to 30.4 A at 40 °C, 29.44 A at 45 °C, 28.8 A at 50 °C, and 27.84 A at 55 °C. The 18 mm width (1 width unit) means it snaps onto DIN rail and occupies one module position. IP20 with conductors connected and the distribution board installed — fine for enclosed panels, not for wet locations.
