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. The TM210 thermal-magnetic release handles overload and short-circuit protection in one unit, so no separate trip unit to order.
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. That 220 kA figure at 240 V is high for a 63 A frame — it handles high-fault utility feeds without cascading upstream breakers. 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.
Physical fit and panel integration
Dimensions: 70 mm deep, 101.6 mm wide, 130 mm tall. 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. No undervoltage release or communication module on this variant — it's a straight thermal-magnetic breaker, no auxiliary electronics to configure.
