Schneider A9F74150: 1P 50A Acti9 iC60N MCB with a curve C thermal-magnetic trip unit and a breaking capacity of 6000 A Icn at 230 V AC 50/60 Hz.
When a breaker of this type trips repeatedly, check the load first; if the breaker itself is damaged or no longer latches, replace it with the same pole number, rating (50A) and curve (C).
