CE logo denotes compliance with European Union Low Voltage Directive
(50-1000 Vac, 75-1500 Vdc). Refer to Data Sheet: 8002 or contact
Bussmann Application Engineering at 636-527-1270 for more information.
General Information:
• GMQ fuse mounts in type HLQ size rejection (size limiting)
carrier (prevents overfusing).
• HLQ carrier comes with 6” of #18 red insulated solid cop-
per wire attached to the line side.
• Customer inserts a #18 insulated solid copper wire into
load side receptacle.
• Size of type GMQ fuses varies with ampere ratings.
• Fuse and knob are an integral one-piece unit. There are no
replacement knobs (caps).
• Units can be panel mounted with a separate steel clip. For
the knockout hole (see above), choose #BK/A-104. For the
keyhole punch type hole, choose #6374 for panels .043” to
.062” thick, or #4909 for panels .030” to .042” thick.
• Do not put tension on line (rear) termianl of fuleholder.
