MCCB for high-fault panel builds
The Siemens SENTRON 3VA2110-7MS36-0JC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C through 70 °C — no derating needed across that span, which simplifies panel thermal budgeting. Its maximum current setting goes to 1 500 A, and the interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
The adjustable trip range (300 A minimum to 1 500 A maximum) covers motor feeder and distribution applications where the load current is well below the breaker's ultimate frame rating. It does not include undervoltage release, phase failure detection, ground-fault monitoring, or communication functions — those are separate variants in the 3VA2 family.
Integration notes
The 3-pole design with line and load lugs accepts copper or aluminum conductors. The shunt trip (STL) requires a separate control voltage — verify polarity and voltage rating from the nameplate before wiring.
