The Siemens Betagard 5SL7163-7RC is a 1-pole miniature circuit breaker with C-curve tripping characteristic, rated 63 A and breaking 10 kA per both EN 60898 and IEC 60947-2.
The 10 kA breaking capacity is the same under both EN 60898 (household/residential standard) and IEC 60947-2 (industrial standard), so this breaker qualifies for either environment — a panel builder can spec it into a residential load center or an industrial sub-panel without recalculating the fault rating. The 63 A rating on a single pole means it protects one phase of a 240 V AC (single-phase) or 440 V AC (multi-phase) circuit, with a power loss of 5.5 W per pole at rated current in hot operating state — worth checking against the enclosure's thermal dissipation budget if densely populated. The 1 MW width (18 mm) keeps panel fill factor tight; a 3-pole version would need 54 mm (three units). Vibration resistance per IEC 60068-2-6 is confirmed — relevant for installations on machinery or near rotating equipment.
