Basic Curve
Derating Curve
Note 2 : The derating curve is derived from the basic curve multiplied by the derating factor of 0.8.
Note 3 : The value of rated current varies with the ambient temperature. It is recommended to use the product within the
derating curve zone.
When using a UL or T
Ü
V approved product, please use the product within the specifi ed range as well as the derating
curve aera.
Note 4 : The measurement method of the derating curve is shown below.
• Test specimen : This product, unused prior to testing.
• Test cable conductor cross sectional area : 5.5mm
2
• Test condition : Power supplied while the specimen is in a stationary state and then measured.
