The Siemens SENTRON 3VA2110-8HM42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying 100 A continuously across its full ambient range from 40 °C up to 70 °C — no derating curve to chase in a warm panel. Breaking capacity runs 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — high enough for most downstream fault scenarios without cascading upstream.
