At 240 V it interrupts 187 kA, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — the full interrupting rating curve you need for selectivity studies. The 400 A frame carries through 50 °C without derating; above that, it steps down to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C.
The 3-pole form factor with 2 HP auxiliary switches mounts directly onto the DIN rail or screw-fixed mounting plate common in industrial enclosures.

The depth is 110 mm (4.33 in), with a width of 138 mm (5.43 in) and height of 248 mm (9.76 in).
No — the 3VA2225-5HN42-0BB0 is a different frame size and rating. The 3VA2340-5HN32-0AB0 is a 400 A, 3-pole MCCB; verify your panel's busbar spacing, cutout dimensions, and cable terminations before substituting. The 138 mm width and 248 mm height may not match the smaller frame.
As a Siemens SENTRON product, this MCCB is designed to meet IEC 60947-2 and UL 489 standards for molded case circuit breakers. RoHS and REACH compliance declarations are standard with the brand's documentation package for this series.
