The Siemens 5SY7316-6 is a SENTRON miniature circuit breaker (MCB) in a 3-pole, B-curve configuration. It's rated for 15 kA breaking capacity per EN 60898, 25 kA per IEC 60947-2, and 5 kA per UL1077 — so it covers both residential-panel (EN 60898) and industrial-panel (IEC 60947-2) coordination requirements in one unit. The B-curve trips between 3 and 5 times rated current, which means it's the right choice for resistive or general-purpose loads where you don't want nuisance trips from motor inrush.
Integration & Mounting
Snaps onto DIN rail via the quick-assembly system, occupies 3 modular width units (54 mm), and can be mounted in any position. Depth is 76 mm, installation depth 70 mm — so it fits standard distribution boards without overhang. The IP20 rating (with connected conductors) is typical for enclosed panel use; no washdown rating, so keep it inside the cabinet.
Standards & Compliance
Dual-rated to IEC/EN 60898-1 (household-type coordination) and IEC/EN 60947-2 (industrial coordination), plus UL1077 for North American supplementary protection. That triple certification simplifies BOM consolidation across regions. Halogen-free and silicon-free construction, sealable, pollution degree 3, overvoltage category III. Operating temperature range -40 to 75 °C, with humidity derating above 55 °C.
