Frequently Asked Questions

What is the LITTELFUSE FLSR.100T fuse used for?

The LITTELFUSE FLSR.100T is a Class RK5 time-delay fuse rated 100 mA, 600 V AC / 300 V DC. It protects motor circuits, transformers, and control panels from overcurrent and short circuits. Its time-delay characteristic allows harmless inrush currents without nuisance opening, making it suitable for industrial equipment with high starting loads.

What are the specifications of the LITTELFUSE FLSR.100T fuse?

The LITTELFUSE FLSR.100T is a Class RK5, time-delay, non-indicating fuse rated 100 mA, 600 V AC, and 300 V DC. It belongs to the FLSR series and is manufactured under part number FLSR.100T. The cylindrical body provides reliable overcurrent protection for industrial circuits requiring high interrupting capacity.

Where to buy the LITTELFUSE FLSR.100T fuse worldwide?

3G Electric supplies the LITTELFUSE FLSR.100T fuse worldwide. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time. We source genuine LITTELFUSE components for industrial maintenance and OEM applications.

How to select the correct LITTELFUSE FLSR series fuse for a motor circuit?

Select the FLSR series fuse based on motor full-load current, voltage (600 V AC or 300 V DC), and starting characteristics. The time-delay feature accommodates inrush without nuisance trips. Verify the interrupting rating meets system fault current. Always consult the LITTELFUSE application guide and local electrical codes for proper sizing.
