The Siemens SENTRON 3VA2063-5HL36-0AF0 is a 3-pole molded case circuit breaker rated for 63 A continuous current, sized for line-protection duty in distribution panels. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, and 75.6 kA at 500 V — figures that cover most industrial service-entrance and feeder applications without needing a current-limiting upstream device. The 63 A rating holds flat across the full operating temperature range from 40 °C to 70 °C, so no derating curve to track when the panel runs warm. Footprint is 105 mm wide by 181 mm tall by 86 mm deep — a standard 3-pole MCCB envelope that fits existing SENTRON panel cutouts and busbar layouts.
At 690 V the rating drops to 3 kA, so it's not a 690 V main breaker unless the available fault current is known to be low.
Integration Notes
Mounts in a standard SENTRON panel or enclosure on the DIN-rail or bolted busbar system. The 86 mm depth leaves clearance behind the door for wiring and accessory pigtails. If you need shunt trip or comms, you're looking at a different variant in the 3VA2 family.
