It is designed for residential and infrastructure panelboards where overcurrent and short-circuit protection of branch circuits is needed. Rated 6 A at 400 V AC means this breaker protects a circuit drawing up to 6 A continuous without nuisance tripping, and the 4-pole (4P) construction switches all three phases plus neutral. The C-curve is the deciding factor for fit: if your load has a high inrush (motors, pumps, transformers) a B-curve might nuisance-trip, while a D-curve would let through more fault energy before opening. C-curve is the standard middle ground for general-purpose branch circuits. Mechanical endurance rated at 10,000 switching cycles typical. Snaps onto standard DIN rail.","metaTitle":"Siemens 5SL6406-7 SENTRON MCB, 4P, C-Curve, 6A, 6kA","metaDescription":"Siemens 5SL6406-7 SENTRON miniature circuit breaker, 4-pole, C-curve, 6 A, 6 kA breaking capacity per IEC/EN.
