The screw terminals accept solid or stranded copper from 0.75 mm² up to 25 mm², torqued to 2.5–3 N·m.","metaTitle":"Siemens 5SL6408-7 SENTRON MCB, 4P C-8A 6kA, 400V AC","metaDescription":"Siemens 5SL6408-7 SENTRON miniature circuit breaker, 4-pole, C-curve, 8 A rated, 6 kA breaking capacity per EN 60898 & IEC 60947-2.
