Overview
The Econ ECS-60 600V 60A fuse is a time delay dual-element Class K5 cartridge fuse designed for use in AC power distribution systems. This versatile protective device provides reliable overcurrent and short-circuit protection with a 200,000 amps interrupt rating. The ferrule-end construction fits standard fuse holders and is widely used in industrial panels, motor circuits, and commercial electrical systems where surge current tolerance is required.
