The Schneider Electric A9N60714 is an Acti9 C120 miniature circuit breaker — a thermal-magnetic MCB rated 80 A at 40 °C, 3 poles, C-curve. It clips onto a 35 mm symmetrical DIN rail and is built for distribution boards in commercial or light industrial panels. Breaking capacity is 5 kA Icu at 230...400 V AC, 50/60 Hz, certified to EN/IEC 60947-2 — that standard covers the breaker's ability to interrupt fault current safely, not just at rated load.
Clip-on mounting on 35 mm DIN rail, 9 module pitches wide (81 mm). Tunnel terminals accept 1...50 mm² rigid or 1.5...35 mm² flexible — that's big enough for a 80 A feed. IP20 finger-safe front, but the busbar area is live when the breaker is on; padlock provision is there for lockout.
