Siemens 3VA2163-7MS32-0JC0 MCCB, 63 A, 330 kA at 240 V

This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V.

Rated 63 A from 40 °C through 50 °C ambient; above that it steps down: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If the panel sits near ovens or in a non-vented enclosure, use the 55 °C or 60 °C row for your continuous load calculation.

Depth 86 mm, width 105 mm, height 181 mm — standard 3-pole MCCB footprint for SENTRON 3VA2 frames. The 105 mm width matches the typical 4-module DIN-rail pitch, so it slots into a multi-breaker lineup without odd spacing. Depth of 86 mm leaves clearance behind a 200 mm deep enclosure door.
