It handles 400 V AC and 60 V DC, with a 1-module-width (18 mm) footprint that snaps onto standard DIN rail. The 400 V AC rating suits single-phase line-to-neutral circuits in 230/400 V systems; the 60 V DC rating opens up control-circuit and battery-backed applications, though DC breaking is limited to single-pole and must respect polarity. The 1-module width (18 mm) is the standard MCB slot — it fits any 18 mm-wide DIN-rail position without adapters. The IP20 rating (with conductors connected) is standard for a DIN-rail device; the handle area is IP40, so accidental tool contact won't trip it.","metaTitle":"Siemens 5SJ4140-7HG41 SENTRON MCB, 1P C-curve, 10 kA","metaDescription":"Siemens 5SJ4140-7HG41 SENTRON miniature circuit breaker, 1-pole, C-curve, 10 kA (EN 60898) / 15 kA (IEC 60947-2), 400 V AC, 60 V DC.

The 5SJ4140-7HG41 is a 1-pole, 18 mm wide device on standard DIN rail, so the mechanical fit is the same, but the electrical ratings and trip curve must be verified against the original design.
