63 A continuous, derated above 55 °C
The Siemens 3VA1163-3ED32-0AA0 is a SENTRON molded case circuit breaker (MCCB) carrying a full 63 A continuous current from 40 °C through 50 °C ambient. Above that, the thermal curve steps down: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. That means in a warm panel — say 55 °C internal ambient — you lose 1 A of headroom; at 70 °C you lose 5 A. The TM210 overcurrent release handles the thermal-magnetic trip characteristic for line protection, not motor or generator duty.
Breaking capacity by system voltage
The interrupting rating drops as system voltage climbs — 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V panel in North America, you're looking at the 440 V figure as the closest reference (32 kA). That's the number to check against your available fault current. The insulation voltage is rated 800 V, so the breaker itself is built for the higher end, but the breaking capacity is what governs selectivity coordination downstream.
Current production, no end-of-life notice
The lifecycle stage is marked current — no phase-out, no last-time-buy window. This is a standard catalog item in the SENTRON 3VA platform. For volume or scheduled BOM commitments, the part is quoted to order through independent distribution; pricing and lead time are confirmed at quote time, not on a shelf.
Panel fit and mounting
Three-pole footprint: 76.2 mm wide, 130 mm tall, 70 mm deep. That's a standard MCCB cutout for a DIN-rail or screw-mount panel. IP40 on the front — fine for a dry indoor enclosure, not for washdown zones. No undervoltage release, no communication module, no ground-fault monitoring on this variant; it's a straight line-protection breaker with the TM210 release.
