What this MCCB delivers for the panel
The Siemens SENTRON 3VA2110-5JP32-0HL0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That makes it a straightforward fit for a 100 A feeder or large motor branch circuit where you want one part number that holds its rating even in a warm enclosure. Interrupting capacity is the headline here: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and still 3.7 kA at 690 V. That SCCR curve means this breaker can sit upstream of a high-fault panel without needing a current-limiting fuse ahead of it — a real advantage when you're coordinating a distribution board where the available fault current is north of 100 kA. The auxiliary switch complement — two auxiliary switches, one trip alarm, one electrical alarm — plus the built-in shunt trip (STL) give the panel builder remote status and trip-initiation capability without adding external relay logic. The communication function allows integration into a higher-level monitoring system, which is useful for a plant that wants to track breaker status without a hardwired marshalling cabinet.
Lifecycle and sourcing posture
For a BOM line that needs this exact 100 A, 3-pole configuration with the shunt trip and auxiliary switch complement, the 3VA2110-5JP32-0HL0 is the right-sized spec. Availability and current pricing are confirmed at quote time against an RFQ through independent distribution.
Panel fit and integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — a standard SENTRON 3VA2 frame footprint that fits the usual DIN-rail or panel-mount pattern. The 86 mm depth (3.39 in) leaves room behind a 200 mm deep enclosure door without crowding the gland plate. Rated for operation from -25 °C to 70 °C ambient, with storage from -40 °C to 80 °C. The 10 W maximum power loss is modest enough that ventilation slots in a standard IP54 enclosure handle the heat without forced cooling.
