What this MCCB carries
The SENTRON 3VA2063-5JQ32-0KC0 is a 3-pole molded case circuit breaker rated for 63 A continuous at 40 °C through 70 °C — no derating needed across that span. The adjustable thermal-magnetic trip unit covers 95 A minimum to 756 A maximum, which gives you a wide coordination window for feeder or main protection. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That's enough SCCR headroom for most industrial distribution panels without cascading upstream. This version is configured for line protection (not motor or generator protection), includes a communication function for remote monitoring or trip indication, and ships with a shunt trip (STL) plus two HQ auxiliary switches. The basic switch underneath is order code 3VA20635JQ320AA0.
Panel fit and mounting
Dimensions are 181 mm high, 105 mm wide, 86 mm deep. That 105 mm width is a standard 3-pole MCCB footprint — it drops into existing SENTRON 3VA panel cutouts and busbar systems without re-drilling. The 86 mm depth leaves clearance for rear-access wiring and busbar connections in a typical 600 mm deep enclosure.
