The interrupting ratings step with system voltage: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 76 kA at 500 V, and 3.8 kA at 690 V.
Communication and auxiliary contacts — what is on board
The auxiliary contacts are factory-fitted, so no field retrofit is needed for basic open/closed indication. Power loss is listed at 10 W maximum, which is modest for a 100 A frame and leaves headroom in a crowded panel's thermal budget.
The 3VA2110-5MQ32-0AC0 measures 105 mm wide, 181 mm high, and 86 mm deep (4.1 in × 7.1 in × 3.4 in). The 86 mm depth is shallow enough for a 200 mm enclosure depth with room for wiring gutters; the 105 mm width is the same as other 3-pole 3VA frames, so a panel laid out for a 100 A SENTRON MCCB accepts this unit without re-spacing the DIN rail.
