The Siemens SENTRON 3VA2110-5JP32-0AG0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels. It carries a 187 kA interrupting capacity at 240 V and 121 kA at 415 V, so it handles high-fault-current scenarios without cascading damage upstream. It does not include undervoltage or ground-fault monitoring — those are separate add-on modules if needed.
The 100 A rating holds across the full ambient range from 40 °C to 70 °C — no derating needed as the panel warms up. That is unusual and simplifies coordination in a crowded enclosure. Interrupting capacity drops as voltage rises: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. For a 480 V panel the 75.6 kA figure is the one to check against your available fault current. Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — standard 3-pole MCCB footprint for this SENTRON frame size. The 86 mm depth matters when fitting into shallow backpanels or retrofit enclosures.
The communication function allows integration with a higher-level monitoring system for load shedding or remote trip indication.
