What this MCCB delivers — and what it doesn't
The Siemens 3VA2110-6HN32-0AD0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C through 70 °C — no derating across the full ambient range, which simplifies panel design when the breaker sits near other heat sources. Three-pole construction, line-protection design, no undervoltage release, no ground-fault monitoring, and no communication function — it's a straightforward thermal-magnetic or electronic-trip MCCB for feeder or branch-circuit duty. Interrupting capacity hits 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is low, so verify the available fault current at that voltage before specifying.
Panel fit and mounting
Dimensions: 105 mm wide, 181 mm tall, 86 mm deep — fits standard MCCB panel cutouts and DIN-rail or screw-mount arrangements typical for SENTRON frames. Rated insulation voltage 800 V, power loss 10 W maximum — budget that heat in the enclosure; the flat derating curve means no extra margin needed for elevated ambient up to 70 °C.
What the interrupting ratings mean for selection
The 242 kA at 240 V is a very high interrupting rating — suitable for large transformer secondaries or high-fault industrial services where available fault current exceeds 100 kA. At 690 V the 3.7 kA limit means this breaker is not a primary choice for 690 V systems unless the fault current is tightly controlled.
