Vac/dc - Traditional Round Body Bolted Style HF Description The LQS Series is a next generation High-Speed Fuse for the protection of power semiconductor devices and is designed in the Traditional North merican Bolted Style package. LQS Series High-Speed Fuses are extremely current limiting and are used to protect power converters, drives and control circuit applications. Designed with lower I t performance characteristics, these fuses provide balanced performance to extend longevity while lowering potentially damaging heat energy to the devices being protected. In addition LQS 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. Such products are commonly found in various industries including pulp and paper industries, cranes and heavy-lifting equipment, processing industries, wastewater treatment plants and large factories and MRO facilities.
