Product Description

The LITTELFUSE FLNR600 is a Class RK5 time-delay blade fuse rated at 600 A, 250 V AC and 125 V DC. Part of the FLNR Series, this non-indicating fuse is designed for overcurrent protection in industrial power distribution systems.

Frequently Asked Questions

What is the LITTELFUSE FLNR600 fuse used for?

The LITTELFUSE FLNR600 is a Class RK5, time-delay fuse rated for 600 A at 250 V AC or 125 V DC. It protects industrial circuits, motors, and transformers from overloads and short circuits, especially where high inrush currents occur. Its non-indicating design suits applications where visual blown-fuse indication is not required.

What are the specifications of the LITTELFUSE FLNR600 fuse?

The LITTELFUSE FLNR600 is a Class RK5, time-delay blade fuse from the FLNR Series. It is rated 600 A, 250 V AC, and 125 V DC. It is non-indicating, meaning it does not show a visual signal when blown. The manufacturer part number is FLNR600, and it is designed for high-current industrial protection.

Where to buy the LITTELFUSE FLNR600 fuse worldwide?

You can source the LITTELFUSE FLNR600 fuse worldwide through 3G Electric, a global industrial equipment distributor established in 1990. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine LITTELFUSE components for industrial applications.

How to select the correct LITTELFUSE FLNR600 fuse for an application?

To select the correct LITTELFUSE FLNR600 fuse, verify your circuit's voltage (250 V AC or 125 V DC max) and continuous current (600 A). Ensure the Class RK5 time-delay characteristic matches your load's inrush profile, such as for motors or transformers. Always consult the manufacturer's data sheet for coordination and interrupting rating requirements.
