The auxiliary switch package is a 4-switch HQ configuration, and the basic switch supplied is order code 3VA2340-7HN32-0AA0. It's a straightforward main breaker — no frills, no hidden surprises, just a high-interrupting 400 A frame. The 400 A rating holds steady up to 50 °C. Above that, it derates: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. That depth is worth checking if you're swapping into an existing panel that was dimensioned around a different MCCB frame — the 110 mm depth is shallower than some older 400 A frames, so it may free up wire-bend space or require a different mounting adapter. Width and height are standard for this class. Power loss at full rated current is 96 W maximum — a useful number for enclosure thermal calculations if you're stacking multiple breakers in a single panel.","metaTitle":"SENTRON 3VA2340-7HN32-0AE0 MCCB, 400 A, 3-Pole, 330 kA at 24","metaDescription":"SENTRON 3VA2340-7HN32-0AE0 molded case circuit breaker, 400 A continuous, 3-pole, 330 kA interrupting at 240 VAC.
