The DC rating per IEC 60947-2 is 15 kA, which matters for DC bus or battery-backed circuits. ## Derating and environmental range Rated current of 0.3 A at 35 °C derates to 0.28 A at 45 °C, 0.27 A at 50 °C, and 0.26 A at 55 °C. The ambient operating range spans –40 °C to 75 °C, with humidity limits of 95% at 55 °C tapering to 35% at 75 °C. IP20 with connected conductors means the terminals are finger-safe once wired; the busbar comb remains exposed unless the panel cover is closed. Combined terminals at both top and bottom accept the busbar and outgoing conductors. The MCB is sealable (tamper-evident cover available) and halogen- and silicon-free — relevant for clean-room or corrosive-environment installations. Any mounting position is permitted, and the supply cord can enter from either end.","metaTitle":"Siemens 5SY6614-7 SENTRON MCB, 4P C-Char 0.3 A, 6 kA","metaDescription":"Siemens 5SY6614-7 SENTRON miniature circuit breaker, 4-pole (3P+N), C characteristic, 0.3 A rated current, 6 kA breaking capacity per EN 60898, 30 kA per IEC 60947-2.

The B curve trips at 3–5× In (suited for resistive or low-inrush loads), whereas the C curve trips at 5–10× In (suited for moderate inductive inrush). Both share the same 4-module DIN footprint and 6 kA / 30 kA breaking capacities, so they are mechanically interchangeable in the same panel position."},{"question":"Where can I buy the 5SY6614-7?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
