The 4.5 kA breaking capacity per EN 60898 covers most residential and light commercial distribution boards; the 6 kA per IEC 60947-2 gives additional headroom for industrial panel applications where the prospective fault current is higher. On the DC side, the 5SY3110-6 is rated 72 V maximum with a 15 kA breaking capacity per IEC 60947-2 — a solid figure for DC auxiliary circuits in control panels, though the 72 V ceiling means it's not a candidate for 110 V DC battery banks. The UL 1077 / CSA C22.2 No. 235 rating at 5 kA confirms acceptance in North American supplementary protection applications. Snaps onto DIN rail via the quick-assembly system, occupies 18 mm (1 width unit), and accepts conductors from 0.75 to 35 mm² solid or stranded at both top and combined terminals. The 5SY3 design is the standard-performance tier of the SENTRON MCB family. A higher-current sibling like the 5SY3132-6 (32 A, same B-curve, same 1-pole footprint) shares the same mechanical envelope — meaning a panel laid out for the 5SY3110-6 can accept the 32 A variant without rewiring the busbar or DIN-rail position, provided the upstream protection and conductor sizing are rated for the higher load. Halogen-free and silicon-free construction, with a sealable option for tamper-proofing in metered or critical circuits. Humidity derating applies: max 95% RH at 55 °C, stepping down to 55% at 70 °C and 35% at 75 °C — relevant for panels in tropical or condensing environments. Touch protection is integrated (finger-safe terminals per IPXXB). The part is classified per DIN EN 61346-2 and DIN EN 81346-2 as function code F (protective device). Compliance documentation (RoHS, REACH, CE, UKCA) is standard with the SENTRON series; UL and CSA listings are confirmed on the nameplate.","metaTitle":"Siemens 5SY3110-6 SENTRON MCB, 1P B 10A 4.5kA","metaDescription":"Siemens 5SY3110-6 SENTRON miniature circuit breaker, 1-pole, B-curve, 10 A, 4.5 kA (EN 60898) / 6 kA (IEC 60947-2).
