The 20 A rating at 30 °C is the headline figure for sizing branch circuits. At elevated panel temperatures the continuous current must be derated: 18.79 A at 40 °C, 18.4 A at 45 °C, and 16.8 A at 55 °C (–). Snap-on DIN rail mount, any position. Sealable for tamper-proofing after commissioning. Halogen-free and silicon-free construction suits installations where off-gassing must be minimized.","metaTitle":"Siemens 5SL6520-6 SENTRON MCB, 20A 1P+N B-curve 6kA","metaDescription":"Siemens 5SL6520-6 SENTRON miniature circuit breaker, 20A, 1P+N, B-curve, 6kA breaking capacity per IEC/EN 60898.
