The Siemens 5SY4413-7 is a 4-pole SENTRON miniature circuit breaker with a C tripping characteristic, rated 10 kA per EN 60898-1 and 20 kA per IEC 60947-2 at 400 V AC. That 20 kA figure under 60947-2 gives selectivity headroom in industrial panelboards where fault currents can exceed the domestic 10 kA ceiling — the breaker clears without upstream devices needing to trip.
DC suitability and voltage limits
Yes, the 5SY4413-7 is suitable for DC applications. The rated DC voltage is 60 V, with a maximum operating voltage of 72 V DC. This makes it usable in DC distribution boards, battery circuits, or control power supplies where 4-pole isolation is needed.
Certifications and environmental range
Certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077 — the UL 1077 rating is 5 kA. Ambient temperature range spans -40 °C to 75 °C, with derating above 55 °C per the humidity limits (95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C). Halogen-free and silicon-free construction.
Mounting position any orientation. Quick assembly system for snapping onto the rail. Sealable — allows locking in the ON position for lockout/tagout. IP20 with conductors connected.
