The Siemens SENTRON 3VA2110-6HN36-0JC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The interrupting capacity is substantial: 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That kind of headroom makes it a fit for high-fault installations where a standard MCCB would weld shut.
At 690 V the interrupting capacity drops to 3.7 kA, which still covers most industrial line-to-line faults on a 690 V system but is worth noting if your available fault current is higher. The shunt trip release (STL) allows remote tripping via a control signal — useful for emergency-stop or interlock circuits. Power loss is 10 W max, manageable for thermal coordination inside a panel.
This MCCB is a panel-mount device — no DIN-rail clip, so plan for screw-mounting on a backplate or in a distribution cabinet. Three poles handle three-phase circuits. It's part of the SENTRON family, which shares a common accessory platform (auxiliary switches, shunt trips, undervoltage releases) across the 3VA range, so stocking one set of spares covers multiple breaker sizes.
