The L70QS series is a next generation high-speed fuse

for the protection of power semiconductor devices and

is designed in the traditional North American bolted style

package.

Part Numbering System

L70 QS 700 .X

Series

L70QS series high-speed fuses are extremely current

limiting and are used to protect power converters, drives

and control circuit applications. Designed with lower I²t

performance characteristics, these fuses provide balanced

performance to extend longevity while lowering potentially

damaging heat energy to the devices being protected.
