That 10 kA interrupting rating means it can safely clear a fault current up to 10,000 amps without welding its contacts or venting arc gas into the panel — essential for downstream coordination in a distribution board where the upstream device may be a 25 kA or 36 kA main breaker. Rated for any mounting position, so you're not stuck with a specific orientation on a crowded rail. The sealable feature means you can lock the toggle position with a lead seal or a padlock hasp accessory — useful for utility-metering applications or where you need to prevent unauthorized reset. Accepts solid conductors up to 25 mm², which is generous for a 10 A breaker; you can land a 4 mm² or 6 mm² feeder without needing a ferrule. Supplementary devices like shunt trips or auxiliary contacts can clip onto the left side without losing the next module position. Halogen-free and silicon-free construction matters in railway, aerospace, or clean-room panels where outgassing from a fault arc can't contaminate sensitive electronics.","metaTitle":"Siemens 5SN4110-7CN SENTRON MCB, 1P C-curve 10 A 10 kA","metaDescription":"Siemens SENTRON 5SN4110-7CN miniature circuit breaker, 1-pole C-curve 10 A, 10 kA per EN 60898, 400 V AC.
