The A9N60785 is a 3-pole Acti9 C120H miniature circuit-breaker rated 80 A at 40 °C with a C curve (magnetic trip at 8 x In ±20 %). The 15 kA Icu breaking capacity at 230…400 V AC 50/60 Hz per EN/IEC 60947-2 means it can safely interrupt a fault current up to that level without upstream cascading — critical for coordination studies in distribution boards. Thermal-magnetic trip technology covers both overload (thermal bimetal) and short-circuit (solenoid) protection in one unit. IP20 finger-safe terminals accept up to 50 mm² rigid or 35 mm² flexible cable with tunnel-type terminals; tightening torque is 3.5 N·m. The 73 mm depth leaves clearance for cover-mounted accessories.
Designed for distribution applications in AC networks at 50/60 Hz. Rated operational voltage 230…400 V AC; rated insulation voltage 500 V AC. Electrical durability 5000 cycles, mechanical durability 20000 cycles. Earth-leakage protection via separate block (not integrated). Local ON/OFF indication on the toggle; handle sealable in OFF or ON position with 0.7 mm cable diameter lock.
