Rated for 400 V AC between phases, this MCB fits 230/400 V TN and TT systems. The 4 MW width (72 mm) occupies four 18 mm DIN-rail positions — standard for a 3P+N breaker in a SENTRON distribution board. Installation depth is 70 mm, with an overall depth of 76 mm — check your enclosure depth if using a shallow gland plate. Screw terminals accept solid or stranded conductors from 0.75 to 25 mm²; tighten to 2.5 to 3 N·m. The neutral conductor is switched (not just linked), so verify the neutral bar arrangement in your panel — this breaker replaces both the phase and neutral protection in one unit, saving a separate neutral link.","metaTitle":"Siemens 5SL6616-7YA SENTRON MCB, 3P+N, C-curve, 16 A, 6 kA","metaDescription":"Siemens SENTRON 5SL6616-7YA miniature circuit breaker, 3P+N, C-curve, 16 A, 6 kA breaking capacity per EN 60898. 400 V AC, 4 MW.
