The Schneider Electric A9F68401 is a 4-pole miniature circuit breaker from the Acti9 iT60 range, rated 1 A with a C-curve trip characteristic. The magnetic trip fires at 8 x In ±20 %.
Terminals accept 1–25 mm² rigid or 1–16 mm² flexible, with a 2 N·m tightening torque. The removable comb busbar makes daisy-chaining multiple poles straightforward in a distribution board.
Dual-rated to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (household). That means it passes both the industrial breaking-capacity test (50 kA Icu at 415 V) and the domestic Icn test (6 kA at 400 V). Suitability for isolation is confirmed under both standards, so you can use it as a disconnecting means.
