The Schneider Electric A9KF71316BQ is an Acti 9 K60H 3-pole miniature circuit breaker (MCB) rated 16 A with a C trip curve and 10 kA breaking capacity, supplied as a set of 4 units.
The 10 kA breaking capacity at 400 V (per IEC 60898-1) tells you this MCB can safely interrupt a fault current up to 10,000 A without welding its contacts or failing catastrophically — that covers most commercial and light industrial distribution boards where the prospective short-circuit current stays under that threshold. The 16 A rating and C curve mean it's sized for a final subcircuit feeding a group of socket outlets or a small motor load; the C curve's wider magnetic trip band avoids nuisance tripping from the inrush of a 3–4 kW motor or a bank of LED drivers.
Panel integration
Snap-on mounting to standard DIN rail (EN 60715). The 3-pole form factor occupies three 18 mm module widths in the distribution board. Supplied as a set of 4 — order one code and get four identical breakers, which simplifies kitting for a multi-circuit panel build.
