What this 100 A MCCB brings to the panel
The Siemens SENTRON 3VA1110-5ED32-0DH0 is a 3-pole molded case circuit breaker rated 100 A continuous at 40 °C — the same rating holds at 45 °C and 50 °C, then gently derates to 91 A at 70 °C. That uninterrupted 100 A band through the first 10 °C above standard ambient buys you thermal headroom in a warm enclosure without upsizing the frame. Interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V — numbers that put this squarely in the high-fault category for industrial mains distribution. At 690 V it still clears 17 kA, so it handles the full IEC utilization range without a current-limiting assist. Line protection design means it's configured for feeder duty out of the box, not motor branch protection.
