The breaker is rated for 400 V AC and 60 V DC, with a breaking capacity of 10 kA per EN 60898 and 15 kA per IEC 60947-2. It's halogen-free and silicon-free, which matters in clean-room or semiconductor-adjacent zones where outgassing can contaminate optics or wafers. ## Standards and approvals context The breaker is designed to EN 60898 (10 kA) and IEC 60947-2 (15 kA) — the two key standards for miniature circuit breakers in Europe and international markets. The IP20 protection (with connected conductors) and IP40 in the handle range are typical for panel-mounted MCBs; the unit is not intended for wet or hose-down environments without an additional enclosure. It's suitable for environment B per EMC classification, meaning immunity to interference is not applicable — standard for passive protective devices.","metaTitle":"Siemens 5SJ4114-7HG42 SENTRON MCB, 1P C-Curve, 10kA EN 60898","metaDescription":"Siemens 5SJ4114-7HG42 SENTRON miniature circuit breaker, 1-pole, C characteristic, 10 kA per EN 60898, 15 kA per IEC 60947-2.
