The interrupting capacity hits 121 kA at 240 V AC, dropping to 75.6 kA at 415 V and 52.5 kA at 440 V, which gives you selectivity headroom for high-fault service entrances or industrial switchboards.
Rated 100 A continuous at 40 °C ambient, and it holds that rating through 50 °C without derating. Above that, the curve steps down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.
Front dimensions are 101.6 mm wide by 130 mm tall, with a 70 mm depth behind the panel. That 4-inch width is standard for a 4-pole MCCB — it occupies the same footprint as the 3VA1110-5ED36-0AA0 sibling, so a panel kitted for that alternate will accept this breaker without drilling new mounting holes or reworking the bus bars.
