Siemens 5SY6208-7 Compact Miniature Circuit Breaker

The Siemens 5SY6208-7 is a compact, two-pole miniature circuit breaker (MCB) from the SENTRON 5SY family, designed to protect individual circuits within electrical distribution panels in commercial and light-industrial settings. It provides 8 A nominal current, is rated for 230/400 VAC operation, and uses a Type C (curve) tripping characteristic suitable for general-purpose protection against both overload and short-circuit conditions. Its short-circuit breaking capacity is 6 kA, and Siemens' data sheets list the device with a depth of about 70 mm (D = 70 mm) in its 2-pole form. Model variants are listed as 5SY6208-7 and 5SY62087; retailers and distributors commonly describe it as a 2-pole, 8 A, 6 kA MCB for 230/400 VAC circuits. The 5SY series MCBs are widely used to protect branch circuits in commercial electrical installations, offering reliable overcurrent protection with a compact footprint that fits standard panelboard enclosures.
