BLS fuses are 1-3/8" long in contrast to
other midget fuses which are 1-1/2". They
provide space-saving, low-cost, protection
to street lighting, metering, control and
electronic circuits.

FLA fuses are 125 volt, pin-indicating time-
delay fuses for protection of control circuit
transformers, solenoids, and other circuits
with high inrush currents. Metal indicating pin
“pops-out” when fuse opens. Pin gives visual
indication of open fuse. Use FLA fuses in
conjunction with special fuseblocks to operate
mechanical signal switches or energize alarm
circuits. Fuses rated 12 amperes and above
have dual-tube construction.
