The 8 A rated current sets the continuous load limit — expect to run it at 80 % (6.4 A) for a comfortable thermal margin. The 415 V AC rating matches three-phase line-to-line voltage in European 230/400 V networks; the maximum operating voltage with multi-phase operation is 440 V. The 18 mm width per pole means a 4-pole unit occupies four adjacent slots — plan your rail fill accordingly. Terminal screws accept solid or stranded copper from 0.75 mm² up to 25 mm²; tighten to 2.5–3 N·m.","metaTitle":"Siemens 5SL4408-7RC SENTRON MCB, 4P C 8A 10kA 415V","metaDescription":"Siemens SENTRON 5SL4408-7RC miniature circuit breaker, 4-pole, C-curve, 8 A, 10 kA breaking capacity at 415 V AC.
