The Siemens SENTRON 3VA2063-5KP32-0DC0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 187 kA at 240 V AC and 121 kA at 415/440 V, dropping to 3 kA at 690 V.
Integration and fit
The 3VA2063-5KP32-0DC0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON panelboard and enclosure cutouts without rework. Power loss is 7.9 W maximum, which keeps heat rise manageable in a densely packed enclosure.
What the interrupting ratings mean for selectivity
For selectivity studies, pair this MCCB with a downstream 65 kA-rated feeder breaker: the 3VA2063's high Icu gives you headroom to coordinate so only the faulted branch opens, not the main.
