Frequently Asked Questions

What is the LITTELFUSE IDSR03.2 fuse used for?

The LITTELFUSE IDSR03.2 is a Class RK5, time-delay fuse rated 3.2 A at 600 V AC/DC. It is used for motor and transformer protection where high inrush currents occur, and its indicating feature allows quick identification of a blown fuse in industrial control panels.

What are the specifications of the LITTELFUSE IDSR03.2 fuse?

The LITTELFUSE IDSR03.2 is a Class RK5, time-delay, indicating fuse rated 3.2 A, 600 V AC, and 600 V DC. It belongs to the IDSR series and is designed for overcurrent protection in industrial equipment. The manufacturer part number is IDSR03.2.

Where to buy LITTELFUSE IDSR03.2 fuses worldwide?

3G Electric supplies the LITTELFUSE IDSR03.2 fuse worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us to source this IDSR series fuse for your facility.

How to select the correct LITTELFUSE IDSR03.2 fuse for an application?

To select the LITTELFUSE IDSR03.2, verify your circuit voltage does not exceed 600 V AC or DC and that the continuous current is 3.2 A or less. The time-delay characteristic handles motor start-up surges. Confirm the Class RK5 rejection clip fits your fuse holder for proper installation.
