L75QS800.X電路保護(hù)的電氣專用保險絲規(guī)格書PDF中文資料

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.

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.

In addition L75QS series fuses have been designed with a

universal mounting option to meet customer requirements

for installation into a variety of application configurations.

Littelfuse POWR-SPEED products offer optimized circuit

protection at the extremely fast speed required to protect

modern day, sensitive, high-power semiconductor devices.
