The Siemens SENTRON 3VA2110-7JQ46-0AA0 is a 4-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. The frame accepts trip units adjustable from 150 A to 1 200 A, so the same physical breaker body can cover a wide range of downstream loads if you swap the electronic trip module.
At 240 V the interrupting rating hits 330 kA, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V. At 690 V it still clears 3.7 kA. Those numbers put it in the high-interrupting category for industrial distribution — useful when you need selectivity with upstream gear and the available fault current is north of 200 kA.
Ground-fault and communication
This variant includes ground-fault monitoring using summation current sensing on L + N conductors, so it can detect leakage without a separate GFCI module. The communication function allows integration into a power-monitoring or energy-management system — useful for a plant that tracks breaker status and load data centrally.
