400 A continuous, full temperature range — no derating needed
That means you don't have to derate for a hot panel — it holds 400 A across the entire operating range, which is uncommon for an MCCB this size. It's a 3-pole unit designed specifically for motor protection, with built-in phase failure detection so it catches a lost phase before the motor cooks. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and still carries 75.6 kA at 500 V. The 5 kA limited-to-1-second rating tells you the short-time withstand for coordination studies. It has a voltage trigger indicator and no communication module — it's a standalone protective device, not a smart breaker. The trip indicator is absent, so you'll need to verify trip status visually at the handle.
The 3VA2440-5MN32-0KA0 measures 138 mm wide by 248 mm tall by 110 mm deep. That's a standard footprint for a 400 A SENTRON frame — it'll drop into existing 3VA panel cutouts without re-drilling. The 110 mm depth (4.33 in) means it fits shallow enclosures where a full-size air breaker won't.
