The Siemens 5SY6413-7 is a SENTRON 4-pole miniature circuit breaker with C-curve tripping, rated 13 A at 35 °C. It carries a dual breaking capacity: 6 kA per EN 60898 and 15 kA per IEC 60947-2 (also 15 kA at DC per IEC 60947-2). That dual rating means it meets the standard for residential/commercial panelboards (EN 60898) while also qualifying for industrial control panels where higher fault current and DC capability are required — one part covers both worlds.
Rated current is 13 A at 35 °C, but the breaker is thermally sensitive: it derates to 12.38 A at 40 °C, 12.05 A at 45 °C, 11.73 A at 50 °C, and 11.38 A at 55 °C.
Mounting position any, so it fits vertical or horizontal busbars. IP20 with connected conductors — protected against finger touch but not water ingress. Suitable for mechanical engineering and industry per the manufacturer's listing.
