The D-curve means the magnetic trip operates at 10 to 20 times In — designed for loads with high inrush, like motor starters, transformers, or discharge lighting, where a B- or C-curve would nuisance-trip on startup. Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2; the higher IEC figure applies when the breaker is used in industrial distribution per that standard, giving you 50 % more fault-interruption headroom over the domestic-rated value. ## Mounting and integration Protection class is IP20 with connected conductors, IP40 in the handle area — sufficient for enclosed panel mounting; not rated for washdown or outdoor exposure without an additional enclosure. ## Sourcing and lifecycle The 5SJ4150-8HG41 is an active, in-production Siemens SENTRON 5SJ4 series MCB. It is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. No official successor has been announced, and the part remains the standard offering for this rating and characteristic.","metaTitle":"Siemens 5SJ4150-8HG41 SENTRON MCB, 1P D-curve, 400 V, 10/15","metaDescription":"Siemens 5SJ4150-8HG41 SENTRON miniature circuit breaker, 1-pole, D-characteristic, 400 V AC, 60 V DC, 10 kA (EN 60898) / 15 kA (IEC 60947-2).
