Overview
The A9F64306 is a Schneider Acti9 iC60 miniature circuit breaker rated 6 A with a C-curve magnetic trip at 8 x In, switching a 3-pole AC load at 220 V. Its 10 kA breaking capacity (Icu) per IEC 60947-2 covers standard distribution panel fault levels. Dual-rated to EN/IEC 60898-1 and EN/IEC 60947-2, it carries a 6 kV impulse withstand voltage and is marked suitable for isolation — meaning it can serve as a disconnecting means in a final subcircuit.
For a 220 V AC distribution board that needs higher interrupting capacity, the A9F87310 offers 42 kA Icu at 10 A, but check the busbar compatibility: the A9F87310 accepts top or bottom comb busbars, while the A9F64306 does not list that option.
