Breaking capacity is rated 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V.
Above that, it derates linearly: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If your panel internal temperature runs hot — say, a sealed enclosure with high-density drives — this derating curve tells you whether the breaker can still carry the load without nuisance tripping.
The 76.2 mm width (three pole, standard 25.4 mm per pole) matches the footprint of the 3VA1 frame family — it drops into the same mounting cutout and bus-bar arrangement as other 3VA1 breakers. Front IP40 protection is typical for switchboard mounting; no special sealing for washdown environments.
Auxiliary contacts and release options
This version ships with 2 auxiliary switches (HQ type) factory-installed. The auxiliary switches are wired separately from the main power path; they share the same mechanical travel as the breaker mechanism.
