The C-curve means it trips between 5 and 10 times rated current — standard for protecting inductive loads like motor starters and contactor coils where inrush is moderate. It is also rated for DC circuits up to 60 V, making it usable in control-voltage distribution. ## Compliance and environmental ratings Rated for overvoltage category III and pollution degree 3, so it is suitable for fixed installations within building distribution or industrial panels where transient overvoltages and conductive dust are expected. The housing is halogen-free and silicon-free, which matters for panels in clean-room or corrosive environments where outgassing must be minimised. IP20 with connected conductors; IP40 in the handle area — standard for panel-mount MCBs, not for wet locations.","metaTitle":"Siemens 5SJ4111-7HG41 SENTRON MCB, 1P C-curve, 10 kA","metaDescription":"Siemens SENTRON 5SJ4111-7HG41 miniature circuit breaker, 1-pole, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2.
