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 indicating 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 a higher rated voltage than the fuse.
* Check specific mounting dimensions before substituting.
† Check characteristics and dimensions for application before substituting.
‡ For 1/10 - 30 amperes, order non-indicating FLNR series fuses.
§ Verify voltage for DC applications.
+ Littelfuse product is a non-renewable fuse.

Motor Protection
SCCR
Effective motor protection is critical in today’s highly
®
automated industrial facilities. POWR-GARD fuses
and protection relays provide optimum protection
for motors in main, feeder, and branch circuits.
The NEC requires Industrial Control Panels be labeled
with their Short-Circuit Current Rating so users and
inspectors can compare their equipment to available
fault currents to avoid potential hazards.
Transformer Protection
Arc-Flash Protection
POWR-GARD fuses provide optimal overcurrent
protection for both the primary and secondary of
control transformers and other regular transformers
above and below 600 volts.
Arc-flash protection relays are intelligent controllers
that safeguard equipment and personnel to prevent
damage, downtime or injury due to arc flash.
Medium Voltage Fuse Protection
Overvoltage Suppression Basics
POWR-GARD medium voltage fuses provide
short-circuit protection for motors and
transformers rated 2,400 to 38,000 Vac.
Overvoltage conditions are an increasing concern
in the electrical industry. Littelfuse has a diverse
portfolio of circuit protection technologies to protect
against voltage transients in multiple applications.
