Reduce Down-Time — A glance at the indicating window
of a FLNR_ID or FLSR_ID Indicator
fuses immediately. If the window is dark, the fuse has
opened. It’s that simple. No fuse testing required.
Machine operators can immediately determine that there is
an open fuse and request maintenance personnel to bring
the proper replacement.
