SENTRON 3VA1110-5FD42-0AA0 — 100 A, 4-Pole MCCB for Line Protection
It carries a breaking capacity of 187 kA at 240 V, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at both 500 V and 690 V — figures that define its fault-interruption capability at the panel's service voltage. The TM210 release integrates thermal (overload) and magnetic (short-circuit) elements, so no separate relay or CT is needed for basic motor or feeder protection.
Above that, the continuous current derates: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. For a panel builder or commissioning engineer, this means the breaker's full 100 A capacity is available in a standard 40 °C enclosure; if the panel runs hotter — near a drive bank or transformer — the load must be trimmed to the derated value or the next frame size selected.
The 4-pole width (101.6 mm) is the key dimension for panel layout — it occupies the same footprint as other 4-pole 3VA1 frame breakers, so a panel designed for a 3VA1110-5EE32-0JA0 or similar sibling accepts this unit without rewiring or bus-bar repositioning.
