Frequently Asked Questions

What is the LITTELFUSE IDSR225 fuse used for?

The LITTELFUSE IDSR225 is a Class RK5, time-delay fuse rated 225 A at 600 V AC/DC. It protects industrial motor circuits, transformers, and branch circuits from overloads and short circuits. Its indicating feature shows a blown fuse, speeding troubleshooting in plants, HVAC, and pump systems.

What are the specifications of the LITTELFUSE IDSR225 fuse?

The LITTELFUSE IDSR225 is a Class RK5, time-delay, indicating fuse rated 225 A, 600 V AC and 600 V DC. It belongs to the IDSR series. The manufacturer part number is IDSR225. It is designed for high-current industrial protection with a visible blown-fuse indicator.

Where to buy the LITTELFUSE IDSR225 fuse worldwide?

3G Electric supplies the LITTELFUSE IDSR225 fuse to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source genuine LITTELFUSE components and support procurement across 14 departments including electrical and power transmission.

How to select the correct LITTELFUSE IDSR225 fuse for a motor circuit?

Select the IDSR225 for motor circuits requiring a 225 A, time-delay, Class RK5 fuse at up to 600 V AC/DC. Time-delay allows for motor inrush without nuisance tripping. Verify the fuse holder is rated for RK5 class and that the interrupting rating meets your system's available fault current. Consult a qualified engineer.
