That 15 kA figure is the Icu at 415 V — the ultimate short-circuit breaking capacity per IEC 60947-2 — and it governs whether this breaker coordinates with the upstream transformer or feeder. The thermal-magnetic trip (LI protection) covers overloads via the thermal bimetal and short-circuits via the magnetic coil. The 100 A rating is the Ir at 40 °C ambient; derate per the manufacturer's curve if the panel ambient runs hotter. The IP20 finger-safe terminals are fine for enclosed distribution boards but not for washdown zones.
Fixed-mount breaker with front-front connections (line and load both front-accessed). Screw terminals accept standard lug or fork terminations. Backplate mounting only — no DIN-rail clip on this frame. The 100 mm width × 130 mm height × 60 mm depth footprint and 25 mm pole pitch fit standard MCCB panel layouts. Neutral is on the left (position 4D — all four poles protected). Power dissipation per pole is 18.7 W at rated current, so a 4-pole breaker dissipates roughly 75 W total. Account for that heat in the enclosure sizing; adjacent devices need air gap or derating above 40 °C.
Certified to EN/IEC 60947-1 and EN/IEC 60947-2 (including Annex H for EMC immunity in industrial environments). Overvoltage category III — rated for fixed-installation distribution boards downstream of the main service entrance. Operating altitude 0–2000 m without derating, 2000–5000 m with derating (air density affects arc extinction and thermal dissipation).
