The Siemens 5SY7413-6 is a SENTRON miniature circuit breaker (MCB) with 4 poles, rated 13 A at AC, and a B tripping characteristic — meaning it trips between 3 and 5 times rated current, suited for resistive or general-purpose loads where inrush is low.
Temperature derating and real-world current
The 13 A rating holds at 35 °C ambient. Above that, derate: 12.48 A at 40 °C, 12.22 A at 45 °C, 11.95 A at 50 °C, 11.67 A at 55 °C, and 11.39 A at 60 °C.
It is halogen-free and silicon-free, and the terminals are sealable for tamper-proofing. Touch protection is built in.
