Acti9 K60 MCB, 20 A, 3P, C Curve — Panel Fit and Protection
The Schneider Electric A9KF71320BQ is an Acti9 K60 miniature circuit-breaker rated 20 A with a C trip curve (magnetic tripping between 5 and 10 times In).
The 20 A rating governs continuous load capacity — this MCB carries 20 A without tripping under normal conditions. The C curve (5–10 x In) means magnetic trip occurs between 100 A and 200 A, suited for circuits with moderate inrush like lighting banks or small motor loads where a B curve would nuisance-trip.
Integration Notes — DIN Rail and Panel Wiring
Terminals accept 1–25 mm² rigid or 1–16 mm² flexible copper; strip 14 mm and torque to 2 N·m. The toggle control provides visual indication of trip status. IP20 finger-safe protection is standard for enclosed panels.
