The Siemens SENTRON 3VA2110-7JQ32-0AA0 is a 3-pole molded case circuit breaker rated for 100 A continuous at 40 °C through 70 °C with no derating across that span — the full 100 A holds at any ambient between 40 °C and 70 °C, which simplifies panel coordination in warm enclosures. Interrupting capacity peaks at 330 kA at 240 V, drops to 242 kA at 415 V and 440 V, and holds 187 kA at 500 V — the 690 V rating of 3.7 kA is the floor, so this breaker is sized for high-fault 480 V distribution panels, not 690 V motor feeders. It carries an onboard communication function, making it suitable for integration into a monitored power distribution scheme where remote trip indication or load data is needed.
Dimensions are 86 mm deep × 105 mm wide × 181 mm tall — the 105 mm width is the standard 3-pole MCCB footprint for panelboard mounting on a DIN rail or direct screw-mount baseplate. Maximum power loss is 10 W, which matters for thermal budgeting in sealed enclosures with multiple breakers in a row.
