The breaker is rated for multi-phase operation at 440 V AC (line-to-line), so it handles 400 V three-phase systems common in European industrial panels. Temperature derating is built into the spec: the 4 A rating holds at 35 °C; at 40 °C it derates to 3.76 A, at 50 °C to 3.5 A, and at 55 °C to 3.37 A. Mounting position is unrestricted — vertical, horizontal, or upside-down — which simplifies layout in tight cabinets. Combined terminals at both top and bottom accept the same conductor for busbar or ring-tongue connections. IP20 with connected conductors is the standard finger-safe rating for a panel-mounted device — no special sealing needed inside the enclosure. No second-source cross-reference exists within the SENTRON family at the same rating and D-curve — the 5SY6204-8CC is the direct order code for a 2-pole, 4 A, D-curve MCB. If a BOM calls for this exact code, there is no parametric substitute that matches the form, fit, and function without a panel re-certification.","metaTitle":"Siemens 5SY6204-8CC SENTRON MCB, 2P D-curve 4A 6kA","metaDescription":"Siemens 5SY6204-8CC SENTRON miniature circuit breaker, 2-pole, D tripping characteristic, 4 A rated at 35 °C, 6 kA breaking capacity per EN 60898.
