The Siemens 5SL6350-7CC is a SENTRON miniature circuit breaker rated 50 A at 30 °C on a 400 V AC system, with a 6 kA breaking capacity per EN 60898. The C-curve tripping characteristic means it handles moderate inrush — typical for motor starters, lighting banks, and general distribution loads — without nuisance trips on start-up. Three-pole design, 3 module widths wide, snaps onto standard DIN rail. Mounting position is unrestricted, so it fits vertical or horizontal panel layouts. Depth is 76 mm (70 mm installation depth), which clears most shallow enclosures.
At 40 °C it derates to 47.15 A; at 45 °C to 45.66 A; at 50 °C to 44.12 A; at 55 °C to 42.53 A.
