Rated 400 V AC (single- or multi-phase) and 220 V DC, with a maximum DC voltage of 250 V. The 10 kA SCCR at 400 V AC per EN 60898-2 means it safely interrupts faults up to that level without cascading upstream — a common requirement for final sub-circuits in commercial and light industrial panels. ## Panel integration Snap-on mounting to DIN rail (35 mm), 1 modular width unit (18 mm wide). The IP20 rating applies with connected conductors, so it is intended for enclosed distribution boards or control cabinets, not open wet areas. Sealable terminals allow lockout-tagout compliance. Accepts any mounting position. Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating above 55 °C. Halogen-free and silicon-free construction. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Complies with IEC/EN 60898-2 and UL1077.","metaTitle":"Siemens 5SY5104-7 SENTRON MCB, C-Curve, 1-Pole, 10 kA","metaDescription":"Siemens 5SY5104-7 SENTRON miniature circuit breaker, C-curve, 1-pole, 10 kA per IEC/EN 60898-2.
