It snaps onto standard DIN rail (35 mm), occupies one modular width unit (18 mm), and accepts wiring through combined top and bottom terminals — no tunnel terminals, so you land the conductor under a clamp, not a screw cage. The 70 mm installation depth leaves room behind the panel door for wiring bends. ## What the ratings mean for your panel B-curve means the magnetic trip operates at 3 to 5 times rated current — it's the standard choice for resistive and general-purpose loads where you want nuisance-tripping protection against motor inrush. The 10 kA rating per EN 60898 covers the majority of domestic and light commercial distribution boards; the 15 kA per IEC 60947-2 applies when the breaker is used in an industrial context with higher prospective fault current. Pollution degree 3 and overvoltage category 3 mean it's rated for the conductive environment inside a typical control cabinet — no special sealing needed for normal panel conditions. The IP20 rating on the body (IP40 in the handle area) assumes connected conductors; it's not a washdown part, but it's fine inside a closed enclosure.","metaTitle":"Siemens 5SJ4135-6HG40 SENTRON MCB, 1P B-Curve, 10 kA","metaDescription":"Siemens 5SJ4135-6HG40 SENTRON miniature circuit breaker, 1-pole, B-curve, 10 kA per EN 60898, 18 mm wide, DIN rail mount.
