Its interrupting capacity hits 121 kA at 240 V, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V — numbers that matter when you're coordinating selectivity downstream of a transformer or tying into a high-fault service entrance.
The 100 A rating holds flat from 40 °C to 50 °C (–); above that it derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C (–). The 121 kA at 240 V is the headline SCCR number for North American 120/240 V split-phase or 240 V delta services; at 415 V (common in IEC 50 Hz plants) it's still 75.6 kA, enough for most distribution boards without a current-limiting fuse upstream.
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON distribution panels or DIN-rail adapter bases. The 27.5 W maximum power loss is moderate for a 100 A frame; factor it into enclosure thermal rise calculations if you're packing multiple breakers in a sealed cabinet.
