Money is wasted each time a circuit opens and halts production.
The indicator window of the IDSR allows maintenance personnel to
pinpoint blown fuses immediately. The circuit can then be tested and
any problem corrected without unnecessary delay, minimizing costly
downtime.
Applications
DC circuits
All general purpose circuits
Motors
Transformers
Solenoids
Fluorescent lighting
All system components with high in-rush currents

Class RK5 Fuse
eliminates all moving parts in a true dual-element design. The IDSR
also provides superior time-delay to withstand minor current surges
without sacrificing protection for sustained overloads or short-
circuit conditions.

MSHA approved.
Indicator fuses. A glance at the indicator window tells if the fuse
has blown. If the window is dark, the fuse has opened. It’s that
simple.
“live” circuit parts while searching for a blown fuse. Other forms of
indication require current to power a light. Littelfuse Indicator fuses
can be identified with the power off.
