Overview
The Littelfuse RLS-30 is a renewable Class H fuse that provides cost-effective overcurrent protection for electrical circuits. Rated for 30A at 600VAC, this fuse is suitable for AC applications where available short-circuit currents do not exceed 10,000 amperes. The renewable design allows for field replacement of internal elements, making it economical for general-purpose feeder and branch circuits in industrial and commercial installations.
