1Use #30707.5 to replace
AGW 7.5 amp.
2Check
specific mounting
dimensions before substituting.
3Check
fuse characteristics and
mounting dimensions for specific
application before substituting.

F or 1/10—30A order non-indicating
FLNR series fuses.
Remember a fuse may be used in
circuits where the fuse's voltage
rating is equal to or greater than
the circuit voltage unless otherwise
stated on the fuse. For example,
the FLSR_ID indicator fuse has a
voltage rating of 75-600 volts. This
fuse can be used on 600 volts, 480
volts, 250 volts, 125 volts, or 75
volts. Never use a fuse in a circuit
having higher voltage than the
fuse.
