The Siemens SENTRON 3VA1163-6ED46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying 63 A continuous at 40 °C with no derating through 50 °C — it holds full ampacity across typical panel ambient temps, only dropping to 58 A at 70 °C.
Interrupting ratings and SCCR planning
Interrupting capacity is 220 kA at 240 V, dropping to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. At 480 V systems the 121 kA at 440 V is the closest published point; for a 480 V panel with available fault current under 100 kA this breaker has headroom.
The 4-pole frame is wider than a 3-pole version — verify panel cutout and busbar spacing if replacing a narrower MCCB. IP40 on the front, so it's suited for dry indoor enclosures; no washdown rating.
