What this MCCB delivers in a dusty panel
The Siemens SENTRON 3VA2063-6HL32-0HA0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full ambient range from -25 °C to 70 °C — no derating needed as the panel heats up near the kiln or conveyor drives. Interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — that covers most industrial fault levels without needing a current-limiting upstream breaker. It carries a shunt trip release (STL) for remote tripping, and the design is line protection — no ground-fault monitoring, no communication module, no undervoltage release. Trip indicator is absent, so plan on a visual check or auxiliary contact if you need remote status.
Panel fit and thermal reality
Footprint is 105 mm wide by 181 mm tall by 86 mm deep — standard SENTRON 3VA2 format. Mounts on a DIN rail or direct-panel screw pattern; verify the existing busbar or cable lug spacing matches the 3-pole pitch before pulling the old breaker out. Power loss is 5.4 W maximum at rated load. Storage range is -40 °C to 80 °C — fine for a spare sitting in a maintenance shed or a truck bed in winter.
How it compares to the 3VA2116-5JP32-0AE0
The 3VA2116-5JP32-0AE0 is a higher-current frame (160 A continuous) with a different trip unit and wider footprint. The 3VA2063-6HL32-0HA0 will not drop into a panel wired for the 2116 frame without re-bussing and re-lugging the load connections. Stick with the 63 A frame if that is what the BOM calls for.
