It carries an 85 kA Icu breaking capacity at 500 V AC 50/60 Hz per EN/IEC 60947-2, making it a distribution-grade breaker for high-fault panels where the available short-circuit current exceeds what a standard 25/36 kA unit can handle. Pollution degree 3 (IEC 60664-1) means it tolerates conductive dust and condensation typical in industrial enclosures — no derating needed for the panel environment itself, just watch the altitude above 2000 m.
The 4-pole version with neutral left (1 x Ir protection on the 4D setting) handles three-phase plus neutral distribution where the neutral is fully rated — not just a switched pole.
IP40 front face and IK07 impact rating keep it safe in a locked panel where only qualified personnel open the door. No earth-leakage module built in — if ground-fault protection is required, add a Vigi module externally.
