Description
Available in both Indicating and Non-Indicating versions,
the FLNR/FLSR series of fuses set the standard for general
purpose fuses. The dual-element design provides advanced
short circuit and overload protection. FLSR series fuses
provide excellent protection for all types of circuits especially
those containing motors.
