The 3-pole configuration handles three-phase loads or three independent single-phase circuits ganged on one handle. Common in small motor control centers, lighting panels, and machine tool cabinets where overcurrent protection for a 0.5 A load is needed. The Version Italy marking is a manufacturing variant — electrically identical to the standard 5SL6 series.","metaTitle":"Siemens 5SL6305-7BB Miniature Circuit Breaker, 0.5A C-Curve","metaDescription":"Siemens 5SL6305-7BB miniature circuit breaker, 0.5A, C-curve, 3-pole, 400V, 6kA breaking capacity.
