The L70QS series is a POWR-SPEED® next-generation, high-speed fuse used for the protection of power semiconductor devices and is designed in the traditional, North American-bolted style package. These fuses protect power converters, drives, and control circuit applications. Designed with lower I2t performance characteristics, the L70QS fuses provide balanced performance to extend longevity while lowering potentially damaging heat energy to the devices being protected. The L70QS series is rated at 700 V ac-dc and is extremely current-limiting. These fuses have been designed with a universal mounting option to meet customer requirements for installation into a variety of application configurations.

POWR-SPEED® brand fuses are optimized for performance and efficiency to help extend equipment life. They perform at the extremely fast speed required to protect modern day, sensitive, high-power semiconductor devices. These 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.
