The Siemens SENTRON 3VA2110-5JP36-0BB0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to the enclosure's thermal limit. Interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and still holds 3.7 kA at 690 V. That makes it a line-protection breaker for high-fault panels where you need selectivity downstream of a transformer or upstream of a motor control center.
At 690 V the 3.7 kA limit means this frame is not for 690 V distribution with high fault current; keep it on 400 V or 480 V systems where the available fault is under 121 kA.
Communication function is onboard, which simplifies integration with a BMS or PLC for load shedding and fault logging.
