100 A MCCB with 187 kA interrupting capacity — current-production SENTRON
The Siemens SENTRON 3VA2010-5HN32-0CH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C through 70 °C, with no derating across that ambient span — per the datasheet, the 100 A rating holds flat from 40 °C to 70 °C. Interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — these are the fault-clearing limits the breaker can safely interrupt without upstream cascade.
Maximum power loss is 16 W at rated load, which governs the enclosure ventilation requirement if multiple breakers are ganged in a sealed panel.
