SENTRON 3VA1163-3ED16-0AA0 — 1-pole 63 A MCCB, line protection
It's built for line protection duty — think feeder circuits, distribution subpanels, or branch protection where you need a compact single-pole footprint. The interrupting capacity hits 53 kA at 240 V AC and still holds 7.5 kA at 415 V, so it handles high-fault utility feeds or transformer secondaries without cascading upstream. The TM210 release gives you fixed thermal pickup at 63 A (Ir min/max both 63 A) and fixed magnetic pickup at 630 A (Ii), so there's no adjustment range — set-and-forget for standard distribution.
Above that, it starts to taper: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. The maximum power loss is 5.8 W, which is modest for a 63 A MCCB and won't drive much internal heat rise on its own.
The 3VA1163-3ED16-0AA0 measures 25.4 mm wide (1 inch) by 130 mm tall (5.1 inches) by 70 mm deep (2.8 inches). That single-pole width matches the standard SENTRON 3VA family footprint, so it clips onto the same DIN rail and aligns with the busbar system. If you're swapping in a panel originally built around a 3VA1020-3ED36-0AA0 or similar 1-pole 3VA, the dimensions and mounting are identical — no rewiring or re-drilling needed.
