The MGN60513 is a C60N miniature circuit breaker from Schneider Electric's Multi9 range, a single-pole thermal-magnetic MCB rated 20 A at 50 °C per EN/IEC 60947-2. The 10 kA Icu at 240 V AC (phase to neutral) tells you it can safely interrupt a fault up to that level without failing; the Ics (service breaking capacity) is 75 % of that, or 7.5 kA, meaning after one high-level fault it's still rated to clear a second one at that lower level. That's a solid spec for a distribution panel feeding motor circuits or general branch loads.
Snaps onto 35 mm symmetrical DIN rail (EN 60715). At 18 mm wide (2 x 9 mm pitches), it takes one module slot in a standard enclosure — no extra space needed for the single pole. Depth is 73 mm, height 81 mm.
