The ESKA 5x20mm T6.3A 250VAC Slow Blow Glass Fuse is a miniature low-voltage fuse designed to protect electrical and electronic circuits against overloads.

As a slow blow / time-delay fuse, it is suitable for circuits where brief current peaks may occur during start-up, such as power supplies, transformers, chargers, electronic equipment, audio devices, radio communication equipment and other electrical devices.

The cylindrical glass body allows quick visual inspection of the fuse condition. The brass contacts with nickel-plated finish help provide good electrical conductivity and corrosion resistance.
