At 35 °C ambient it carries the full 40 A; at 40 °C it derates to 37.6 A, at 45 °C to 36.36 A, at 50 °C to 35.04 A, and at 55 °C to 33.68 A — so if the panel runs hot, the actual load must be reduced accordingly. Halogen-free and silicon-free construction, rated for pollution degree 3 (industrial environments with conductive or dry non-conductive pollution). Energy limitation class 3 — limits let-through energy under fault conditions. Sealable for anti-tamper applications. Operating temperature range -40 °C to 75 °C, with humidity limits: max 95% up to 55 °C, max 55% up to 70 °C, max 35% up to 75 °C.","metaTitle":"Siemens SENTRON 5SY6240-6CC MCB, 40A, 2P, B-Curve, 6kA","metaDescription":"Siemens SENTRON 5SY6240-6CC miniature circuit breaker, 40A rated, 2-pole, B characteristic, 6kA breaking capacity per EN 60898.
