Overview
The A9F64320 is a Schneider Acti 9 iC60 miniature circuit breaker rated 20 A with a C-curve magnetic trip at 8 x In ±20 %, switching a 3-pole AC network at 240 V. Its 10 kA breaking capacity (Icu) per IEC 60947-2 covers standard distribution panel duty. It is marked suitable for isolation per both IEC 60898-1 and IEC 60947-2.
Compared to the A9F79325 (same 3-pole, 25 A, C-curve), the A9F64320 carries a lower 20 A rating and a 10 kA Icu versus 25 kA on the A9F79325. Against the A9F77320 (3-pole, 20 A, C-curve, 6 kA Icu), the A9F64320 offers a higher 10 kA Icu, making it the choice when the prospective short-circuit current sits between 6 kA and 10 kA.
