The A9F08413 is a 4-pole Acti9 iC60H miniature circuit breaker rated at 13 A with a D tripping curve. At 380-415 V AC the breaking capacity is 15 kA Icu, still sufficient for typical distribution boards. The thermal-magnetic trip unit provides overload protection via the bimetal and short-circuit protection via the solenoid, with a separate earth-leakage block (Vigi) available as an add-on. Overvoltage category IV and pollution degree 3 suit it for main incoming panels in industrial environments. The IP20 finger-safe terminals are standard for enclosed distribution boards.
The 4-pole form factor means it switches all four poles simultaneously — no neutral pole left unprotected. Terminals accept 1-25 mm² rigid or 1-16 mm² flexible wire (double terminal top and bottom), with a strip length of 14 mm and tightening torque of 2 Nm. The toggle actuator provides manual on/off control with a trip indicator that shows the breaker has tripped (not just been switched off). The 78.5 mm depth and 91 mm height fit standard enclosure cutouts.
