Product Description

The LITTELFUSE L70QS Series is a very-fast-acting bolt-on semiconductor fuse rated at 200 A and 700 V AC/700 V DC (MPN L70QS200.V). This AC/DC voltage type fuse is designed for overcurrent protection in power electronic applications.

Frequently Asked Questions

What is the LITTELFUSE L70QS200.V fuse used for?

The LITTELFUSE L70QS200.V is a very-fast-acting bolt-on semiconductor fuse used for overcurrent protection in power electronic applications such as variable frequency drives, UPS systems, and rectifiers. It protects sensitive components from short circuits and overloads in AC/DC circuits up to 700 V.

What are the specifications of the L70QS200.V fuse?

The L70QS200.V is a 200 A, 700 V AC/700 V DC very-fast-acting semiconductor fuse from the LITTELFUSE L70QS Series. It features a bolt-on mounting style and is designed for high-speed overcurrent protection in power electronics. The voltage type is AC/DC.

Where to buy LITTELFUSE L70QS200.V fuses worldwide?

You can source the LITTELFUSE L70QS200.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 series fuse for my application?

To select the correct L70QS fuse, match the voltage rating (700 V AC/DC) and current rating (200 A for the L70QS200.V) to your circuit requirements. Ensure the bolt-on mounting style fits your fuse holder. Consult the LITTELFUSE application guide for coordination with semiconductor devices and ambient temperature derating.
