What this MCCB carries and where it fits
The Siemens SENTRON 3VA2163-5HN32-0AC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity hits 187 kA at 240 V AC, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. That spread covers most industrial distribution panels where high-fault service entrance or feeder protection is the job. Rated insulation voltage is 800 V, so it handles 690 V line-to-line without creeping into the margin. The auxiliary switch pack comes as two HQ-style switches built in — no separate add-on module needed for status feedback to a PLC or annunciator.
Panel fit and footprint
Dimensions are 105 mm wide by 181 mm tall by 86 mm deep. That 86 mm depth is the key number for enclosure back-panel clearance.
