primary (ul and Csa)
To assist in the selection of fuses, the following chart recommends the maximum primary fuse rating in amperes. The
first number shown is the maximum overcurrent protection when the primary current is less than 2 amps and the overcurrent
protection device is rated for 300%. The second number shown (italic) is recommended when the primary is less than 2 amps
and the overcurrent device is to be rated at 500% of rated current. Where only one number is indicated, the primary is 2 amps
or more and one rating of over current protection is shown as optimal. Choose the next higher fuse rating if these numbers do
not correspond with standard fuse selections.
