The Siemens SENTRON 3VA2110-7MN36-0CA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Its interrupting capacity hits 330 kA at 240 V and 242 kA at 415 V, which puts it squarely in the high-fault category for industrial main feeders or large motor branch circuits.
Interrupting capacity across voltage levels
At 415 V and 440 V it still holds 242 kA; at 500 V it drops to 187 kA. At 690 V the interrupting capacity falls to 3.7 kA — that's the point where you need to check whether the available fault current at the panelboard stays under that limit. For a 480 V distribution panel in North America, the 187 kA at 500 V covers most utility transformer sizes.
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep. That 105 mm width is the standard 4-module footprint for SENTRON 3VA molded case breakers — it clips onto a DIN rail or mounts directly to a backplate. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
