The Siemens SENTRON 3VA2110-7MS36-0AJ0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling.
Interrupting capacity drops from 330 kA at 240 V to 242 kA at 415 V and 440 V, then to 187 kA at 500 V, and falls sharply to 3.7 kA at 690 V. That steep decline at 690 V means this breaker is not intended for primary 690 V distribution — use it on the 400 V class bus where it still delivers 242 kA, enough for most industrial secondary feeders. That simplifies panel coordination when the breaker sits near heat sources like drives or transformers.
