Siemens 5SL6108-7BB — 8 A C-curve MCB for residential and infrastructure panels
Mounting and wiring — 18 mm per pole, screw terminals rated to 25 mm²
Width is 18 mm (one modular unit), so this breaker occupies a single slot on a standard DIN-rail distribution board. 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.
