What this MCCB brings to the panel
The SENTRON 3VA2163-6HN32-0BC0 is a 3-pole molded case circuit breaker rated 63 A continuous across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That 63 A holds steady at every temperature step, so you can populate a warm cabinet without recalculating the main feeder. Interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V, and still 121 kA at 500 V — numbers that put this squarely in high-fault-duty switchgear. At 690 V it drops to 3.7 kA, so if you're on a 690 V line, check the available fault current against that ceiling. It ships with an undervoltage release (UVR) and two HQ auxiliary switches built in — the basic switch order code is 3VA2163-6HN32-0AA0. No communication function, no ground-fault monitoring, no voltage trip. This is a straight line-protection breaker, not a smart breaker.
Panel fit and dimensions
Footprint is 105 mm wide, 181 mm tall, 86 mm deep — a standard 3-pole MCCB envelope that drops into most DIN-rail or panel-mount assemblies without re-drilling. The 86 mm depth leaves clearance for rear-connected busbars in a typical 600 mm deep enclosure.
