The A9F68101 is a 1 A C-curve miniature circuit breaker from Schneider Electric's Acti9 iT60N range, built for distribution-level overcurrent protection.
The removable comb busbar is pre-installed, so you can bus multiple poles without extra hardware. Terminals accept 1–25 mm² rigid or 1–16 mm² flexible cable; strip length is 14 mm, torque to 2 N·m. IP20 B finger-safe protection is adequate for enclosed panel use.
The C-curve magnetic trip activates at 8 x In ±20 % — meaning the 1 A unit holds through motor inrush and transformer energization but clears fast on a hard short. That 8x multiplier is the standard C-curve threshold (5-10x In range), so it coordinates predictably with downstream C-curve MCBs in a radial distribution scheme.
