The Siemens 3VA2110-5JP32-0DA0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. Its 3-pole design handles line protection duty, with a rated insulation voltage of 800 V and breaking capacities that scale with system voltage: 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.
Panel fit and thermal performance
Dimensions are 86 mm deep, 105 mm wide, and 181 mm tall — a standard 3-pole MCCB footprint for DIN-rail or panel-mount installation. Power loss is 12.5 W maximum, which is modest for a 100 A frame and keeps internal panel temperature rise manageable in a sealed enclosure. Operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C. The continuous current rating holds flat at 100 A from 40 °C through 70 °C — no thermal derating curve to calculate for typical industrial panel environments.
