10 gl/gg Class Fuses D Type Ambient Temperature WEG gl/gg fuses are sized to operate in environments at 5±5 C. Fuses installed in environments with different temperatures have different heat dissipation rates, reducing or increasing their rated current. Thus, the T a factor must be applied when sizing WEG gl/gg fuses. Ambient temperature factor T a T a factor Ambient temperature ( C) T a ambient temperature factor of WEG gl/gg fuses Altitude The installation of WEG gl/gg fuses must not exceed,000 meters above sea level, according to IEC Above such altitude, the low atmospheric pressure directly influences the fuse thermal dissipation. Thus, the K alt factor must be applied when sizing WEG gl/gg fuses..05 K alt altitude factor K alt factor of the fuse rated current ,000,500,000,500 3,000 3,500 4,000 4,500 5,000 5,500 Altitude (m) K alt factor related to the application altitude of WEG gl/gg fuses gl/gg Fuses NH Blade Contact and D Type
