What this MCCB carries and why it matters
The Siemens SENTRON 3VA2163-7KP32-0AA0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across its full ambient range — it holds that rating from 40 °C through 70 °C without derating, which simplifies panel sizing in warm enclosures or near other heat sources. Its interrupting capacity reaches 330 kA at 240 VAC and 242 kA at 415 VAC, so it handles high-fault utility feeds or transformer secondaries where standard MCCBs would need upstream fusing. The ETU850 electronic trip unit provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves — line protection design, not motor or generator protection, so it is sized for distribution feeders and branch circuits.
Panel fit and mounting
The 3VA2163-7KP32-0AA0 occupies 105 mm width, 181 mm height, and 86 mm depth — a standard 3-pole MCCB footprint that drops into SENTRON mounting plates or DIN-rail adapters without re-drilling gland plates. Front IP40 protection means it is suited for enclosed panel mounting where incidental tool contact is the only exposure; not rated for washdown or outdoor installation without an additional enclosure.
