Main circuit terminals are screw-type, accepting solid or stranded conductors: 2×(1…2.5 mm²) and 2×(2.5…6 mm²), or AWG 14…10. Front face carries IP20 touch-safe protection; the busbar and live terminals behind the cover are not finger-safe until the cover is installed. No auxiliary contacts are included (0 auxiliary contacts), so any remote status signaling requires a separate auxiliary switch block snapped onto the side. ## Environment and durability The 25g / 11 ms shock resistance covers most industrial vibration and occasional mechanical impact during transport or panel door slam. Mechanical endurance of the main contacts is typically 100 000 operations; the maximum switching rate at AC-3 duty is 15 operations per hour. For a motor starting once every few minutes on a conveyor or pump, that rate is not a constraint — it only matters for high-cycle applications like rapid reversing or jogging.","metaTitle":"Siemens SIRIUS 3RV1021-1GA10-0FJ0-ZX95 MCP, 6.3 A, 100 kA @","metaDescription":"Siemens SIRIUS 3RV1021-1GA10-0FJ0-ZX95 motor circuit breaker, 6.3 A continuous, 100 kA breaking capacity at 400 V AC, CLASS 10 trip.
