The Siemens SENTRON 3VA2110-5MN32-0AG0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient temperature range from 40 °C to 70 °C — no derating needed in a warm panel.
At 415 V this MCCB interrupts 121 kA, and at 240 V it handles 187 kA — figures that give solid SCCR headroom for most industrial panel designs. At 690 V the rating drops to 3.7 kA, so it is not a candidate for 690 V main feeders; its home is on 400 V motor circuits where the high fault current capability supports selective coordination with downstream breakers.
Motor protection and auxiliary configuration
Maximum power loss is 10 W, so heat dissipation inside a sealed enclosure is manageable.
