The Schneider Electric A9KF71310 is a 3-pole miniature circuit breaker from the Acti9 K60 series, rated 10 A with a C-curve trip characteristic. It is a thermal-magnetic MCB designed for distribution in AC networks at 50/60 Hz.
IP20 finger-safe front is standard for enclosed panel use. The toggle control provides local on/off switching with a contact-position indicator absent — you read the handle position directly.
The C-curve with magnetic trip at 5…10 x In means it holds through transformer inrush and motor starting currents up to about 50–100 A for short durations, then trips instantaneously on a hard short. Electrical and mechanical endurance are both 20,000 cycles, which is typical for a distribution MCB. The part is tropicalised to class 2 per IEC 60068-1, meaning it withstands damp heat — relevant for installations in high-humidity environments. Operating altitude is 0…2000 m; relative humidity up to 95% at 55 °C. Pollution degree 2 covers normal industrial environments with only non-conductive pollution.
