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.
Applications
• Service entrance switches
• Transformers
• Switchboard mains and feeders
• Motor control central mains and motor branch circuits
• All general purpose circuits
Features/Benefits
• Indication
• Dual-element design
• Available without indication
• Current limiting
