Siemens SENTRON 3VA2110-5JQ32-0KH0 — 100 A MCCB with 187 kA Interrupting Capacity
At 415 V and 440 V the rating holds at 121 kA, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V, which covers the common low-voltage industrial range. That simplifies panel sizing: the breaker delivers its nameplate 100 A even when the cabinet is running hot. Physical footprint is 86 mm deep by 105 mm wide by 181 mm tall, a standard SENTRON 3VA form factor that fits the same panel cutouts and busbar risers as other 100 A frames in the series.
Maximum power loss is 10 W, which is modest for a 100 A frame and keeps internal cabinet heating manageable.
