The C-curve means it holds through moderate inrush (typically 5–10× rated current) before tripping, which suits mixed loads with some motor or transformer starting current. Rated current derates with ambient temperature: 3.82 A at 40 °C, 3.63 A at 50 °C, 3.53 A at 55 °C — if your panel runs warm, you need to account for that or the breaker may nuisance-trip. ## Deployment context — panel integration Designed for DIN-rail mounting in residential and infrastructure distribution boards. The sealable design (padlockable handle) allows lockout/tagout isolation — if it's not locked, it's not safe. Halogen-free and silicon-free construction means it won't release corrosive gases in a fire, which matters for ventilation-constrained enclosures or sensitive electronics sharing the same cabinet. Touch protection on the terminals reduces arc-flash risk during troubleshooting.","metaTitle":"Siemens 5SL6404-7CC SENTRON MCB, 4-pole C 4A, 6kA","metaDescription":"Siemens 5SL6404-7CC SENTRON miniature circuit breaker, 4-pole, C-curve, 4 A rated, 6 kA breaking capacity per EN 60898.
