482 Series Fuseholders for Alarm Indicating Fuses
482 Series Fuseholders
Description
RoHS
Ideal for telecommunications and control panel circuits, the
482 Series fuseholder is designed for use with Littelfuse
481 Alarm Indicating Fuses. Each holder is designed to
accept other manufacturers’ replacement fuses as well.
The fuseholder is available in three versions:
PCB Mount - 15A:
Can be soldered directly to a printed
circuit board. Rated up to 15 amperes. Available in single
pole or gangable up to 20 poles. Fuseholder is keyed to
prevent insertion of 20 ampere fuse.
Panel Mount - 20A:
Available in a single pole version rated
up to 20 amperes. Large leads for wire attachment.

NOTE: The 20 ampere single pole holder is designed to
accept all fuse ratings up to 20 amperes.
20 ampere fuseholders should be spaced 12.7mm (0.50”)
apart when loaded to maximum capacity, center to center
to insure proper heat dissipation under normal operation.
Heatsinking may be required for operation in higher
ambient temperatures or alternate configurations.
All terminals dimensions should be taken with fuse
installed.
