SECTION 1
Recommendations For Overcurrent Protection con’t...
Primary (UL and CSA)
in amperes. The fi rst 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 (in brackets)
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.
