It snaps onto a DIN rail (quick assembly system) and occupies 3 modular width units (54 mm). The IP20 rating with connected conductors means it's intended for enclosed panel mounting — not for wet or outdoor locations. ## Key ratings and what they mean for your panel Rated 6 kA per EN 60898-1 and 15 kA per IEC 60947-2 at 400 V AC. The higher IEC figure covers industrial installations where fault current may exceed the domestic EN rating — so this breaker can handle a 15 kA prospective short-circuit current without welding its contacts. For DC circuits, it's rated 15 kA at 60 V (max 72 V) per IEC 60947-2. Under UL 1077, the interrupting rating is 5 kA — that's the figure for North American supplemental protection applications. B-curve means the magnetic trip operates at 3 to 5 times rated current — typical for resistive and general-purpose loads where inrush isn't severe. Pollution degree 3 and overvoltage category III suit it for fixed industrial installations where transient overvoltages are common. The operating temperature range (-40 °C to 75 °C) covers cold storage and hot machine cabinets without derating. ## Compliance and documentation Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 — covers both IEC and North American supplemental protection. Halogen-free and silicon-free construction, sealable terminals, and a combined top/bottom terminal design for daisy-chaining. The manufacturer provides RoHS and REACH declarations as part of the standard documentation package.","metaTitle":"Siemens SENTRON 5SY6325-6 Miniature Circuit Breaker, 3P B-Cu","metaDescription":"Siemens SENTRON 5SY6325-6 3-pole B-curve MCB.
