The Siemens 5SY6608-8 is a SENTRON 5SY6 miniature circuit breaker with a D tripping characteristic, rated 8 A at 400 V AC across four poles (3P+N).
Combined top and bottom terminals simplify daisy-chaining in a distribution board.
Compliance documentation — RoHS, REACH, UL, IEC — is provided with the shipment; the UL 1077 / CSA C22.2 No. 235 rating is 5 kA at AC for North American installations.
6 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC; for UL 1077 / CSA C22.2 No. 235 it is rated 5 kA at AC.
Solid or stranded conductors from 0.75 to 35 mm².
Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Both are 4-pole SENTRON MCBs on the same DIN-rail footprint, but the 5SY7140-8CC carries a higher current rating and different breaking capacity — verify the load and fault-current requirements before substituting.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
