The Schneider Electric A9F06420 is an Acti9 iC60H miniature circuit breaker (MCB) rated for 20 A with a B curve, 4 poles, and a thermal-magnetic trip unit. It's built for distribution panels and protects branch circuits against overloads and short circuits, with a 42 kA Icu breaking capacity at 12-133 V AC and 30 kA at 220-240 V AC per EN/IEC 60947-2.
It's rated for isolation per both standards, carries overvoltage category IV, and pollution degree 3 — so it's designed for the harsh electrical environment of a main distribution board.
Terminals accept double conductors: 1-25 mm² rigid or 1-16 mm² flexible, with a 14 mm strip length and 2 N.m torque. IP20 finger-safe terminals are standard for enclosed panels. The white housing with toggle and trip indicator gives clear visual status on the rail.
The A9F06420 is a current-production Acti9 iC60H MCB.
