It's a 3-pole unit in a 3-module-width housing (54 mm), designed for residential and infrastructure branch-circuit protection where the B-curve handles resistive and light inductive loads without nuisance tripping from inrush. The B-curve (3-5 In) trips fast on short circuits but holds through normal motor-start inrush for small pumps or fans; it's the standard choice for general-purpose lighting and socket circuits. Thermal derating is published: at 40 °C ambient the continuous rating drops to 5.64 A, at 55 °C to 5.04 A. The breaker mounts in any position and fits a standard DIN rail with 70 mm installation depth. Sealable terminals are provided, which matters for utility-metering or rental applications where tamper evidence is required. Halogen-free and silicon-free construction meets low-smoke material specs for public-building installations.","metaTitle":"Siemens 5SL6306-6 SENTRON MCB, 3P B 6A 6kA","metaDescription":"Siemens 5SL6306-6 SENTRON miniature circuit breaker, 3-pole, 6A, B-curve, 6kA breaking capacity per EN 60898.
