Product Description

The LITTELFUSE L70QS Series is a very-fast-acting bolt-on semiconductor fuse rated at 90 A and 700 V AC/700 V DC (MPN L70QS090.V). This AC/DC fuse is designed for overcurrent protection in power electronic circuits.

Frequently Asked Questions

What is the LITTELFUSE L70QS090.V fuse used for?

The LITTELFUSE L70QS090.V is a very-fast-acting bolt-on semiconductor fuse used for overcurrent protection in power electronic circuits, such as inverters, drives, and UPS systems. It protects sensitive components from short circuits and overloads in AC or DC applications up to 700 V.

What are the specifications of the L70QS090.V fuse?

The L70QS090.V is a 90 A, 700 V AC/700 V DC very-fast-acting semiconductor fuse from the LITTELFUSE L70QS Series. It features a bolt-on design for secure mounting and is rated for both AC and DC voltage types. The manufacturer part number is L70QS090.V.

Where to buy LITTELFUSE L70QS090.V worldwide?

You can source the LITTELFUSE L70QS090.V fuse through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine LITTELFUSE components.

How to select the correct L70QS fuse for my application?

To select the correct L70QS fuse, match the voltage rating (700 V AC/DC) and current rating (90 A) to your circuit requirements. Ensure the bolt-on mounting fits your fuse holder. For semiconductor protection, choose a very-fast-acting fuse like the L70QS090.V to minimize let-through energy. Consult LITTELFUSE application notes for coordination.
