What this MCCB does in the panel
The Siemens SENTRON 3VA1096-2ED32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 16 A at 40 °C through 50 °C. Breaking capacity hits 52.5 kA at 240 V AC and 32 kA at 415 V — enough to clear high-fault conditions on a distribution bus without upstream coordination issues.
The 16 A rating holds flat from 40 °C to 50 °C, then derates: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C.
Front-panel IP40 protection suits it for enclosed distribution boards. Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON 3VA panel cutouts.
Breaking capacity varies by system voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. For DC network applications, the 3VA molded case circuit breaker device manual (linked under Service & Support) covers the derating and configuration rules.
