The Siemens SENTRON 3VA2110-5MN32-0AJ0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, holding that rating across the full ambient temperature range from 40 °C to 70 °C without derating — that 100 A is the same at 70 °C as it is at 40 °C, which simplifies panel thermal budgeting in a crowded enclosure. At 240 V it reaches 187 kA, and at 690 V it drops to 3.7 kA — the part is designed for 400 V class distribution, not 690 V motor circuits. This unit is designated for motor protection, with phase failure detection built in.
For BOM freeze and PCN-watch purposes, the 3VA2110-5MN32-0AJ0 is under change control; any revision to its design or supply status would trigger a manufacturer notification.
The 86 mm depth leaves clearance for rear-connected busbars in a typical 400 mm deep enclosure.
