The D characteristic means it tolerates inrush currents 10–20× rated — built for motor, transformer, or lighting ballast loads where the start-up spike would trip a B or C curve. Breaking capacity is 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No.235, which covers most industrial panel secondary faults. The 3P+N configuration switches the neutral pole, so it's suited for TN-S or TT systems where neutral isolation is required. Conductor terminations accept solid or stranded from 0.75 to 35 mm², with a screw-terminal torque range of 2.5–3.5 N·m. The top and bottom terminals are combined (line/load interchangeable), and the breaker carries touch protection (IP20 with conductors connected). Depth is 76 mm (70 mm behind panel); the sealable cover option allows lockout-tagout compliance without removing the breaker. Four width units (72 mm) — verify DIN rail space before panel layout.","metaTitle":"Siemens 5SY6608-8CC SENTRON MCB, 4P D 8A, 6kA","metaDescription":"Siemens 5SY6608-8CC SENTRON miniature circuit breaker, 4-pole D-curve 8 A AC, 6 kA breaking capacity per EN 60898.
