It's designed for residential and infrastructure branch-circuit protection per EN 60898 and IEC 60947-2, with a 10 kA breaking capacity under both standards — meaning it can safely interrupt fault currents up to 10,000 A without welding or arcing over. ## Real-world ratings and derating At 40 °C it derates to 5.76 A, at 45 °C to 5.64 A, and at 55 °C to 5.37 A — so if your panel runs hot, size the load accordingly. DC rating tops out at 72 V, so it's not a DC distribution breaker above that. Mounting position is unrestricted — horizontal, vertical, upside-down, doesn't matter. IP20 with conductors connected, meaning finger-safe terminals but no washdown tolerance. Sealable, halogen-free, silicon-free — relevant if the panel spec calls for low-corrosion materials in a sealed enclosure.","metaTitle":"Siemens 5SL4406-6 SENTRON MCB, 4P B-Char 6A 10kA","metaDescription":"Siemens 5SL4406-6 SENTRON miniature circuit breaker, 4-pole, B-curve, 6 A rated at 30 °C, 10 kA breaking capacity per EN 60898.
