BRITISH STYLE–
SEMICONDUCTOR PROTECTION FUSES
The Edison British Style semiconductor protection fuses
include a 660VAC line utilizing new filler technology. These
Replacement Table — “T” to “F” (660V)
New “F” Range
new fuses have greatly reduced peak let-through current
and energy under fault conditions and hence extend fuse
protection capability. They can be recognized by the letter
“F” in their catalog number. Application and technical data
for these 660VAC “F” fuses and the original line of 240VAC
British “T” type fuses are presented on the following pages.
“F” Range
This is a superior design of fuses in the same physical
package as the “T” range.
Equivalent Ratings
This table shows the suggested equivalent ratings to
replace a “T” with an “F”.
Because of the new design technology it has been possible
to obtain the equivalent energy let-through I 2 t with a higher
amp rated fuse hence reducing the possibility of premature
operation.
This table gives a range of suggested acceptable new “F”
type to replace the earlier “T” type.
To upgrade your protection to the new “F” series select a
fuse rating within the range shown that suits your circuit
inrush requirements. You will still have the same or better
protection of your semiconductor devices.
It should be remembered that to protect devices we must
consider the energy let-through of the selected fuse. The
label amp rating will relate to the full load current and the
circuit inrush amps.
The suggested replacements are based on:
a. Similar surge withstand to normal circuit overloads.
b. Lower total I 2 t let-through.
This gives enhanced reliability due to the use of a higher
current rated fuse which avoids nuisance operation and still
gives improved short-circuit protection.
