SENTRON 3VA1010-2ED36-0BC0 — 100 A MCCB with Undervoltage Release
It carries a 52.5 kA breaking capacity at 240 V, derating to 32 kA at 415 V and 13.6 kA at 440 V — figures that govern its fault-interruption capability on a 400 V three-phase system.
The rated ultimate short-circuit breaking capacity (Icu) is specified per IEC 60947-2: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Above that, derate linearly: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Maximum power loss is 27.5 W — relevant for enclosure heat calculation when multiple breakers are ganged in a panel.
Footprint: 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in) — fits standard SENTRON 3VA panel cutouts. The two auxiliary switches HQ mount internally and share the breaker's compact depth; no external add-on block needed. The undervoltage release (UVR) is wired to a separate control voltage; verify polarity and that the supply is stable — a dip below dropout will trip the breaker.
