It interrupts fault currents up to 10 kA per EN 60898 and IEC 60947-2, which means it safely clears a short-circuit up to that level without welding its contacts or cascading failure upstream in the distribution board. Occupies 1 modular width unit (18 mm) on a DIN rail, with an installation depth of 70 mm and overall depth of 76 mm. Mountable in any position, which simplifies layout in crowded enclosures. Sealable terminals (padlockable) let the panel builder lock out the circuit for maintenance isolation. Halogen-free and silicon-free construction, which matters for panels in environments sensitive to outgassing (e.g., clean rooms, medical equipment, or sealed enclosures near sensitive electronics). Mechanical service life of 10 000 operating cycles typical.","metaTitle":"Siemens 5SL4108-7 SENTRON MCB, 1P C 8A 10kA","metaDescription":"Siemens SENTRON 5SL4108-7 miniature circuit breaker, 1-pole, C-curve, 8 A, 10 kA breaking capacity per EN 60898.
