Product Description

The LITTELFUSE KLLU Series Class L Time-Delay Bolt-On Fuse (MPN KLLU3500X) is a 3.5 kA, 600 V AC, 300 V DC industrial fuse with a bolt-on body. It provides time-delay operation for overcurrent protection in high-current applications.

Frequently Asked Questions

What is the LITTELFUSE KLLU3500X fuse used for?

The LITTELFUSE KLLU3500X is a Class L time-delay bolt-on fuse used for overcurrent protection in high-current industrial applications such as switchboards, panelboards, and motor control centers. Its time-delay characteristic allows it to withstand temporary inrush currents without nuisance opening.

What are the specifications of the LITTELFUSE KLLU3500X fuse?

The LITTELFUSE KLLU3500X is a KLLU Series Class L time-delay bolt-on fuse rated 3.5 kA, 600 V AC, and 300 V DC. It features a bolt-on body for secure mounting in high-current circuits. The manufacturer part number is KLLU3500X.

Where to buy the LITTELFUSE KLLU3500X fuse worldwide?
