The Schneider A9F07670 is an Acti9 iC60H miniature circuit breaker — a 1P+N unit rated at 0.5 A with a C-curve, designed for distribution boards on DIN rail. The 10 kA Icn per EN/IEC 60898-1 covers the domestic/commercial rating side. Dual-standard certification means it satisfies both the industrial (60947-2) and installation (60898-1) standards, so it works in mixed environments without a coordination headache.
At 0.5 A rated current (In), this is a low-current MCB — it protects a control transformer primary, a small power supply, or a signal-loop feeder, not a motor or a general-purpose socket circuit. The C-curve (magnetic trip at 8 x In ±20 %, so 4 A nominal) means it tolerates moderate inrush without nuisance tripping, which suits transformer or capacitive loads. The thermal-magnetic trip unit gives both overload (thermal bimetal) and short-circuit (solenoid) protection in one package. The 10 kA Icn per EN/IEC 60898-1 is the standard domestic rating; the 70 kA figure is what the industrial spec calls for.
The 1P+N configuration puts the neutral on the left, switched with the phase.
