What this MCCB carries and where it fits
The Siemens 3VA2110-6HN36-0AJ0 is a SENTRON molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C. Breaking capacity is 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. At typical 480 V distribution levels that 187 kA rating means it handles high-fault scenarios without cascading upstream — a real advantage in a main or subfeed position. Three-pole construction, line-protection design (no ground-fault monitoring, no undervoltage release, no communication function). The auxiliary switch block carries two auxiliary switches plus one trip alarm switch (HP type) — enough for remote status and trip indication back to a PLC.
Dimensions and panel fit
Footprint is 105 mm wide, 181 mm tall, 86 mm deep. That 105 mm width is the standard 3-pole MCCB envelope for this class — it lands on a DIN rail or bolts into a panel-mount base without surprises. Depth of 86 mm leaves room for rear busbar connections in a typical switchboard.
