Fuseholder Re-Rating
For 25°C ambient temperatures, it is recommended that fuseholders be operated at no more than 60% of the nominal current rating
established using the controlled test conditions specified by Underwriters Laboratories.
The primary objective of these UL test conditions is to specify common test standards necessary for the continued control of
manufactured items intended for protection against fire, etc. A copper dummy fuse is inserted in the fuseholder by Underwriters
Laboratories, and then the current is increased until a certain temperature rise occurs.
The majority of the heat is produced by the contact resistance of the fuseholder clips. This value of current is considered to be the
rated current of the fuseholder, expressed as 100% of rating.
Some of the more common, everyday applications may differ from these UL test conditions as follows: fully enclosed fuseholders,
high contact resistance, air movement, transient spikes, and changes in connecting cable size (diameter and length).
Even small variations from the controlled test conditions can greatly affect the ratings of the fuseholder. For this reason, it is
recommended that fuseholders be de-rated by 40% (operated at no more than 60% of the nominal current rating established
using the Underwriter Laboratories test conditions).
* In some cases for these categories the ratings, agency approvals and specifications vary by part number and
are presented here as ranges representing the whole series.
