Frequently Asked Questions

What is the LITTELFUSE FLSR.150T fuse used for?

The LITTELFUSE FLSR.150T is a Class RK5 time-delay fuse rated 150 mA, 600 V AC / 300 V DC. It protects motor circuits, transformers, and control panels from overloads 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.150T fuse?

The LITTELFUSE FLSR.150T is a Class RK5, time-delay, non-indicating fuse rated 150 mA, 600 V AC, and 300 V DC. It belongs to the FLSR Series and is designed for branch-circuit protection. The manufacturer part number is FLSR.150T. It provides reliable overcurrent protection in industrial control panels and motor circuits.

Where to buy LITTELFUSE FLSR.150T worldwide?

3G Electric supplies the LITTELFUSE FLSR.150T fuse worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time. We source genuine LITTELFUSE components to support your maintenance and production needs anywhere in the world.

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

To select the correct LITTELFUSE FLSR series fuse, match the voltage rating (600 V AC or 300 V DC) to your system. The time-delay feature handles motor starting inrush. Choose an amp rating 125–150% of the motor full-load current. For a 150 mA application, the FLSR.150T is appropriate. Always consult the motor nameplate and local codes.
