A 10 amp glass fuse is a cylindrical fuse consisting of a glass casing containing a thin metal wire. This fuse protects electrical circuits by interrupting the power supply when the current exceeds the 10 amp limit, preventing damage to electrical devices or potential fires. Glass fuses are commonly used in household appliances, electronics, and vehicle systems. They can be easily checked for a blowout since the glass allows visual inspection to see if the wire has melted. They are essential for ensuring the safety of electrical systems.
