Where the following conditions apply, fuses complying with this standard are deemed capable of operating satisfactorily without further qualification;Normal temperature: -5°C to 40°C;
Installation altitude ≤ 2000 m above sea level;
Clean air with relative humidity ≤ 50% at 40°C;
Higher humidity permitted at lower temperatures (e.g., 90% at 20°C);
Moderate condensation may occur due to temperature variation.
For other operating conditions, please contact the manufacturer.
