Thermal derating and operating envelope

Rated 10 A at 35 °C ambient, the 5SY4210-7CC derates to 9.19 A at 40 °C, 8.75 A at 45 °C, 8.29 A at 50 °C, and 7.81 A at 55 °C. In a sealed, uncooled enclosure near other heat sources, size the continuous load against the 40 °C or 45 °C column — not the 35 °C nominal. Ambient humidity influence is specified: max 95% RH up to 55 °C, tapering to 55% at 70 °C and 35% at 75 °C.

Halogen-free and silicon-free construction, sealable. Neutral conductor is not switched (2-pole, both phases switched). Suitability for mechanical engineering and industry per the manufacturer designation.
