The higher IEC rating gives headroom if the installation standard calls for industrial coordination. ## Derating and temperature At 40 °C it derates to 30.4 A, at 50 °C to 28.8 A, and at 70 °C to 24.64 A. Storage range is wider, but the operating limits are what govern in-service reliability. Halogen-free and silicon-free construction, which matters for clean-room or high-reliability installations where outgassing can contaminate contacts or optics. IP20 with the distribution board installed and conductors connected. Degree of pollution 2 and overvoltage category III.
