The 4-pole (3P+N) configuration covers three-phase circuits with a switched neutral, common in industrial distribution panels feeding mixed loads. Ambient temperature derating is built into the spec: at 40 °C the continuous rating drops to 15.36 A, at 50 °C to 14.7 A, and at 60 °C to 14.02 A. In a hot-strip mill or near furnace zones where ambient runs 55 °C, the effective rating is 14.37 A — a real constraint when sizing branch circuits for motor control centers or drive auxiliaries. Compliance documentation is available from the brand for RoHS, REACH, and the relevant IEC/EN standards (EN 60898, IEC 60947-2). The part carries IP20 protection with connected conductors, so it requires enclosure in a panel or distribution board rated for the environment. Snap-on mounting to DIN rail, any position. The 72 mm width occupies 4 modular units (each 18 mm), so it fits standard 4-MU cutouts in distribution boards. Sealable cover is standard, which matters for lockout/tagout or meter-sealing requirements.","metaTitle":"Siemens 5SY4616-5 SENTRON MCB, 4-Pole 16A, Char A, 10/20kA","metaDescription":"Siemens 5SY4616-5 SENTRON miniature circuit breaker, 4-pole 16 A, tripping characteristic A, 10 kA (EN 60898) / 20 kA (IEC 60947-2).
