That 100 A holds steady at every 5 °C increment, so it's sized for a 100 A feeder or branch circuit in a warm enclosure without recalculating the thermal curve. The 800 V rated insulation voltage gives headroom for 480 V and 600 V class systems; the 440 kA interrupting rating at 240 V drops to 330 kA at 415 V and 52.5 kA at 690 V, so verify the available fault current at your service voltage before committing the BOM line. ## Breaking capacity curve — what trips up specifiers The 7.7 W maximum power loss is low enough that ventilation in a standard IP2X enclosure is sufficient; no forced cooling required.","metaTitle":"Siemens 3VA2110-8KQ32-0AA0 SENTRON MCCB, 100 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2110-8KQ32-0AA0 molded case circuit breaker, 100 A continuous, 3-pole, 440 kA at 240 V.

Both are SENTRON 3VA platform breakers sharing the same 105 mm width, 181 mm height, and 86 mm depth footprint, so they fit the same panel cutout and busbar spacing. However, the 3VA2110 carries additional wiring for the communication function and ground-fault summation current transformer, so the panel must have those connections provisioned. Verify the auxiliary wiring diagram before swapping."},{"question":"What compliance documentation does this brand provide for 3VA2110-8KQ32-0AA0?","answer":"Siemens SENTRON MCCBs are designed to IEC 60947-2 and UL 489 standards.
