At 40 °C it derates to 76.16 A, at 45 °C to 74.16 A, at 50 °C to 72.16 A, at 55 °C to 70 A, and at 60 °C to 67.84 A. If your panel runs warm — and most enclosed distribution boards do — the 40 °C figure is the one to spec against, not the 35 °C headline. Certified to IEC/EN 60898-1 and IEC/EN 60947-2. Halogen-free and silicon-free construction. Sealable for lockout/tagout. Touch protection is built in.","metaTitle":"Siemens 5SY4580-7 SENTRON MCB, 80 A C-Curve, 2-Pole, 10 kA","metaDescription":"Siemens SENTRON 5SY4580-7 miniature circuit breaker, 80 A rated, C-curve, 2-pole (1P+N), 10 kA breaking capacity per IEC 60898.

The swap is mechanical; the difference is the current rating — 80 A here versus the lower rating of the 5SY4140-7.
