The Siemens 5SY7613-7 is a 4-pole (3P+N) miniature circuit breaker from the SENTRON 5SY7 series, rated 13 A with a C-curve tripping characteristic. It protects branch circuits in industrial control panels and distribution boards against overloads and short circuits, with a breaking capacity of 15 kA per EN 60898 and 25 kA per IEC 60947-2 at 400 V AC. The 13 A rating suits smaller branch circuits feeding contactor coils, control transformers, or lighting groups.
Sealable cover and touch protection are built in.
Humidity tolerance: max 95% up to 55 °C, derating to 35% at 75 °C. Overvoltage category III, energy limiting class 3. Suitable for mechanical engineering and industrial environments per the manufacturer.
