Description

The L75QS series is a next generation high-speed fuse

for the protection of power semiconductor devices and is

designed in the traditional round body bolted style package.

V = 5 (35–200 A)

L75QS series high-speed fuses rated at 750 V dc 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.
