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. 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.
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.
The 10 W maximum power loss is modest enough that ventilation slots in a standard IP54 enclosure handle the heat without forced cooling.
