Terminal design includes touch protection per the product feature. The breaker is sealable, halogen-free, and silicon-free — relevant for installations with sensitive contacts or where environmental compliance documentation is required downstream. ## Operating conditions and approvals Overvoltage category 3 and energy limiting class 3 confirm it coordinates with standard upstream protective devices. Rated for 50 Hz AC supply, with a maximum operating voltage of 440 V in multi-phase configuration. The single-pole design does not switch the neutral conductor.","metaTitle":"Siemens 5SL6108-7BB SENTRON MCB, 1P C-curve 8 A 6 kA","metaDescription":"Siemens 5SL6108-7BB SENTRON miniature circuit breaker, 1-pole, C-curve, 8 A rated, 6 kA breaking capacity per EN 60898/IEC 60947-2, 400 V AC.
