The Schneider Electric A9K14306 is an Acti9 iK60N miniature circuit breaker — 3 poles, C-curve, rated 6 A at 30 °C. It breaks 4500 A at 400 V AC (EN/IEC 60898-1), which is the standard fault level for residential and light-commercial distribution boards in most of Europe and Asia. Thermal-magnetic trip with a magnetic threshold of 5 to 10 times In means it holds motor inrush and transformer magnetising current without nuisance tripping, yet still clears a hard short fast. The C-curve is the default for general-purpose distribution — lighting, small motor loads, socket circuits — where you need a bit of headroom above the B-curve. IP20 finger-safe, rated for isolation, and carries a padlocking option.
Accepts 1 to 25 mm² rigid copper — plenty for the 6 A load circuit. The ON/OFF toggle gives a visible isolation point; the padlock hasp accepts a standard 4 mm shackle for LOTO procedures.
