Siemens SENTRON 5SY3004-7KL — C-curve MCB, 4 A, 1P+N
The Siemens 5SY3004-7KL is a SENTRON miniature circuit breaker in a 1P+N configuration — one protected pole plus a switched neutral — with a C-curve tripping characteristic rated at 4 A and a breaking capacity of 4.5 kA per EN 60898 at 230 V AC. Single-phase operation is rated up to 250 V AC. Rated current derates with ambient temperature: 4 A at 30 °C, 3.84 A at 40 °C, and 3.76 A at 45 °C — factor that into the load schedule if the panel runs warm. Depth behind the panel is 70 mm; overall depth is 76 mm.
Integration notes
The neutral conductor is switched internally — no external neutral link needed for the 1P+N configuration. The breaker is sealable, halogen-free, and silicon-free. Vibration-resistant per IEC 60068-2-6.
