The Siemens SENTRON 3VA2110-6HN32-0BL0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Breaking capacity is the headline here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. The drop to 3.7 kA at 690 V tells you this is a 600 V class breaker; at 690 V the arc extinction limits its interrupting ability, so verify the available fault current at your system voltage.
Built-in undervoltage release and internal wiring
The UVR is factory-integrated; no field kit to add. The basic switch inside is order code 3VA21106HN320AA0 — that is the internal switching mechanism. If you ever need to replace just the switch block (not the entire breaker), that is the part number to reference. The breaker itself has a trip indicator and no voltage-trigger or communication function; it is a straight electromechanical MCCB.
What the 100 A rating means in practice
That is unusual for a compact MCCB; many competitors need a 0.8 derating factor at 60 °C. This one holds 100 A all the way. The closest functional sibling in the SENTRON family is the 3VA1110-5EF32-0AM0. That is also a 100 A, 3-pole MCCB but in the 3VA1 frame (compact, lower breaking capacity) versus this 3VA2 frame (higher interrupting ratings, more auxiliary options). The 3VA1110-5EF32-0AM0 will not drop into the same panel footprint without checking the mounting hole pattern and busbar spacing — the 3VA2 frame is physically larger (105 mm wide vs the 3VA1's 70 mm). If your panel was laid out for a 3VA1, this 3VA2 will not fit without re-drilling the backplate.
Environmental and compliance range
No ground-fault monitoring version is included; this is a straight overcurrent and short-circuit protection device.
