The Siemens 5SY5213-7CC is a 2-pole SENTRON miniature circuit breaker with C-curve tripping, rated 13 A at 35 °C and 10 kA DC breaking capacity per IEC 60947-2.
DC Ratings and Temperature Derating
The current rating is temperature-dependent: 13 A at 35 °C, 11.53 A at 40 °C, 10.72 A at 45 °C, 9.85 A at 50 °C, and 8.89 A at 55 °C. In a warm panel (40 °C+ ambient), the effective continuous current is lower than the 13 A label — size the upstream conductor and load accordingly.
Operates from -40 °C to 75 °C, with humidity limits per the spec (max 95% at 55 °C, derating to 35% at 75 °C). Mounts in any position via the quick-assembly DIN-rail system; installation depth is 70 mm. Halogen-free and silicon-free construction.
