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. Designed specifically for motor protection, it includes built-in phase failure detection and a trip indicator, so a motor losing a phase on a conveyor or pump line will trip before single-phasing the winding.
Interrupting capacity and selectivity
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
The breaker ships with one auxiliary switch and one trip alarm switch (HP type) factory-fitted — enough to signal a tripped state to a PLC or annunciator without adding a separate accessory. No undervoltage release, no ground-fault monitoring, and no communication module are included; this is a straightforward motor-protection MCCB for a standard MCC bucket or distribution panel.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that fits SENTRON distribution boards and most DIN-rail or screw-mount panel layouts. Maximum power loss is 10 W, so heat dissipation inside a sealed enclosure is manageable.
