The Schneider Electric A9N60708 is a 1-pole miniature circuit breaker from the Acti9 C120 range, rated 80 A at 40 °C with a C-curve trip characteristic. It clips onto a 35 mm symmetrical DIN rail — standard for panel and enclosure builds — and occupies 3 x 9 mm pitches (27 mm wide). The thermal-magnetic trip unit handles distribution-level overcurrent and short-circuit protection, with a magnetic tripping limit of 8 x In ±20 %.
Rated 5 kA Icu at 230...400 V AC 50/60 Hz per EN/IEC 60947-2. The limitation class is 3 per the same standard, meaning it lets through less energy during a fault, which helps with downstream coordination.
Installation and wiring constraints
Tunnel-type terminals accept 1...50 mm² rigid or 1.5...35 mm² flexible cable. Wire stripping length is 15 mm for both top and bottom connections. Tightening torque: 3.5 N·m. The toggle gives local ON/OFF indication, and the contact position indicator confirms the state visually. Padlock provision is included for lockout/tagout procedures.
