Derating	In cases where the ambient temperature surpasses 40°C, the product's overload protection features exhibit minimal sensitivity to temperature variations. It is imperative to adjust the current rating (Ir) to guarantee optimal performance in elevated-temperature conditions. Moreover, when operating at altitudes exceeding 2000m, it is crucial to account for shifts in dielectric strength and the impact of air temperature reduction. Consequently, a derating procedure becomes essential to ensure safe and reliable operation in such environments.
