What this MCCB carries and where it fits
The Siemens 3VA2110-5JP32-0AE0 is a SENTRON molded case circuit breaker sized for line protection in distribution panels. Rated 100 A continuous at 40 °C through 70 °C with no derating across that range, so it holds its full ampacity in a warm enclosure — that's a solid spec for a crowded panel. Three poles, interrupting capacity of 187 kA at 240 V and 121 kA at 415 V, meaning it clears high-fault scenarios on the secondary side of a step-down transformer without cascading upstream.
Panel fit and integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard MCCB footprint that drops into most SENTRON panelboards and DIN-rail adapters without re-drilling. The 10 W maximum power loss at full load keeps internal cabinet temperature rise manageable; no forced cooling needed in a typical 600 mm wide enclosure. Communication function is onboard, so it can report status and trip events to a PLC or BMS without an add-on module.
Interrupting ratings across voltages
The 3VA2110-5JP32-0AE0 delivers 187 kA at 240 V, 121 kA at 415 V and at 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That 690 V figure is low enough to flag — if your system runs at 690 V and fault current exceeds 3.7 kA, this breaker is not the right pick. The high 187 kA at 240 V suits it for transformer secondary or bus-duct protection where available fault current is high.
