The C-curve (tripping characteristic class C) means the breaker holds up to 5–10× rated current for short periods — typical for motor and lighting circuits with moderate inrush. At 4 A, that's 20–40 A magnetic trip threshold. The 10 kA breaking capacity at 415 V AC per EN 60898 tells you it can safely interrupt a fault current up to 10,000 A without welding contacts or cascading failure upstream. Rated for 415 V AC with multi-phase operation up to 440 V AC maximum, and single-phase operation at 250 V AC. The supply frequency is 50/60 Hz, so it covers both common mains standards globally. ## Physical fit and mounting Mounting position is any orientation — no derating needed for horizontal or inverted install. Sealable design allows locking the toggle in off position for lockout/tagout compliance.","metaTitle":"Siemens 5SL4304-7RC SENTRON MCB, 3P C-curve 4A 10kA","metaDescription":"Siemens SENTRON 5SL4304-7RC miniature circuit breaker, 3-pole, C-curve, 4 A rated, 10 kA breaking capacity per EN 60898.
