The Siemens SENTRON 3VA2163-0KP36-0AA0 is a 3-pole molded case circuit breaker rated for 63 A continuous current, carrying an ETU850 electronic trip unit that supports adjustable overload and short-circuit protection curves. The front face is IP40, so it's suited for enclosed panel mounting where incidental tool contact is the only exposure. The ETU850 trip unit provides adjustable N-conductor protection from OFF to 160% in steps, plus a communication function for remote monitoring or integration into a higher-level energy management system. The 63 A rating holds flat across the full ambient range from 40 °C to 70 °C — no derating curve to track when the panel runs hot.
At 105 mm wide × 181 mm tall × 86 mm deep, this MCCB fits standard SENTRON 3VA mounting footprints. The depth of 86 mm (3.39 in) means it clears most 200 mm deep enclosures with room for rear cable routing. Verify the busbar adapter or lug kit compatibility if retrofitting into an existing panel — the 3VA frame shares the same mounting hole pattern as earlier 3VL series, but the accessory catalog changed.
