The B-curve (3–5× In) means it trips fast on short-circuit but tolerates moderate inrush — typical for resistive and general-purpose loads in final sub-distribution. The 2-pole form factor (both L and N switched) is common in Italy for single-phase final circuits where the neutral must be switched alongside the line.","metaTitle":"5SL6240-6BB Miniature Circuit Breaker 400 V 6kA, 2-pole B, 4","metaDescription":"5SL6240-6BB miniature circuit breaker, 400 V, 6 kA, 2-pole B-curve, 40 A, Italy variant.
