Description
The Fast Acting Glass Fuse 5×20mm is a miniature cartridge fuse designed to provide rapid overcurrent and short-circuit protection for electronic and electrical equipment. Its fast-acting characteristic enables it to open the circuit almost immediately when excessive current is detected, helping to protect sensitive components from damage.
It features a transparent glass body that allows easy visual inspection of the fuse element and is commonly used in power supplies, control panels, test instruments, consumer electronics, and industrial control systems. The standard 5×20mm size is widely compatible with IEC fuse holders.
