Frequently Asked Questions

What is the LITTELFUSE FLSR03.2 fuse used for?

The LITTELFUSE FLSR03.2 is a Class RK5 time-delay fuse rated 3.2 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and other inductive loads from short circuits and sustained overloads. Its time-delay characteristic prevents nuisance opening during inrush currents, making it suitable for industrial control panels and HVAC equipment.

What are the specifications of the LITTELFUSE FLSR03.2 fuse?

The LITTELFUSE FLSR03.2 is a Class RK5, time-delay, non-indicating fuse. It is rated 3.2 A, 600 V AC, and 300 V DC. It belongs to the FLSR series and has a cylindrical body. The manufacturer part number is FLSR03.2. It is designed for branch-circuit protection where high inrush currents occur.

Where to buy LITTELFUSE FLSR03.2 fuses worldwide?

3G Electric supplies the LITTELFUSE FLSR03.2 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?

To select the correct LITTELFUSE FLSR series fuse, match the voltage rating (600 V AC or 300 V DC) and ensure the amp rating (e.g., 3.2 A) exceeds the motor full-load current. The time-delay feature handles startup inrush. Always consult the motor nameplate and local electrical code. 3G Electric can assist with sizing guidance.
