The 330 kA breaking capacity at 240 V AC means it can interrupt a fault up to that level without the arc climbing into the buswork; at 690 V it still holds 52.5 kA, which covers most industrial service-entrance and feeder applications. ## Breaking capacity across voltages — selectivity headroom The interrupting ratings span the common industrial voltages: 330 kA at 240 V, 242 kA at both 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. For a panel designer chasing full selectivity downstream of a transformer, those numbers give you room to coordinate with smaller branch breakers without cascading the whole board. At 55 °C it derates to 96 A, at 60 °C to 94 A, and at 70 °C to 90 A. Dimensions are 181 mm high, 105 mm wide, 86 mm deep; it fits the standard SENTRON 3VA mounting footprint, so a panel laid out for a 3VA1 or 3VA2 frame accepts this unit without re-drilling the backplate. ## Auxiliary contacts and release configuration This variant ships with 2 auxiliary switches (HQ type) built in — no separate add-on block to order and snap on. If your safety circuit requires a UVR or GF trip, you need a different suffix.","metaTitle":"Siemens 3VA2110-7MN32-0AC0 SENTRON MCCB, 100A, 330kA at 240V","metaDescription":"Siemens 3VA2110-7MN32-0AC0 SENTRON molded case circuit breaker, 100A rated continuous current, 330kA breaking capacity at 240V AC.
