It switches both phase and neutral, with the neutral pole switching but not protecting — the overcurrent trip is on the phase side only. ## Where it fits and how it mounts It mounts in any position, which helps when you're packing a tight enclosure. The IP20 rating applies with conductors connected — fine inside a distribution board but not for wet locations. ## Thermal derating and environmental limits At 40 °C it derates to 18.8 A, and at 45 °C to 18.2 A — so if your panel runs hot, size the upstream protection accordingly.","metaTitle":"Siemens 5SN6020-7CN SENTRON MCB, 1P+N, 20 A, C-Curve, 6 kA","metaDescription":"Siemens 5SN6020-7CN SENTRON miniature circuit breaker, 1P+N, 20 A rated, C-curve, 6 kA breaking capacity per EN 60898.
