SENTRON 3VA2110-5JP32-0KL0 — 100 A MCCB with ETU550 trip unit
It carries a breaking capacity of 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — so the interrupting rating drops sharply above 500 V, which matters for 690 V distribution panels where the available fault current must be verified against that 4.25 kA ceiling.
Above that, it derates linearly: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. Dimensions are 181 mm high, 105 mm wide, 86 mm deep, which fits standard SENTRON 3VA panel cutouts; the 105 mm width is the same as the 3VA1 frame, so a panel laid out for a 3VA1010 will accept this 3VA2110 without re-drilling the mounting plate.
Trip unit and auxiliary configuration
It also includes a voltage trigger and a trip indicator. Communication function is present, so it can integrate with higher-level monitoring systems.
