The 3VA2063-5HL32-0CC0 is a SENTRON 3-pole molded case circuit breaker rated for 63 A continuous current, with no derating across the full 40 °C to 70 °C operating range — meaning it holds its full 63 A rating even in a warm panel without downsizing the branch. Its interrupting capacity hits 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V — so on a 480 V distribution board it clears 75.6 kA faults without cascading upstream, which covers most industrial service-entrance and feeder applications.
At 105 mm wide, 181 mm tall, and 86 mm deep, this MCCB occupies a standard 3-pole molded-case footprint — the same width as most 100 A frame breakers — so it drops into an existing DIN-rail or panel-mount cutout without re-drilling the gland plate. Power loss is 7.9 W maximum, which keeps internal cabinet temperature rise manageable even when multiple breakers are ganged in a distribution block.
Built-in release and auxiliaries
The basic switch core is 3VA20635HL320AA0, meaning the release and aux configuration is integral to the assembly — not a field-added kit — so the BOM line is one order code, not a pile of accessories.
