The Siemens SENTRON 3VA2110-5JQ32-0AJ0 is a 3-pole molded case circuit breaker (MCCB) rated for line-protection duty, carrying a continuous current of 100 A across its full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity steps with system voltage: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At typical 400 V distribution levels the 121 kA rating handles high-fault scenarios common in industrial switchgear without requiring upstream current-limiting fuses.
