Introduction to Screw Fuse
A screw fuse is a type of electrical fuse that is commonly used in electrical circuits to protect against over - current conditions. It consists of a fuse element, usually made of a metal alloy with a low melting point, enclosed in a ceramic or glass body. The screw - type design allows for easy installation and replacement in a fuse holder. When the current flowing through the fuse exceeds its rated value, the fuse element melts, breaking the circuit and preventing damage to electrical equipment and potential fire hazards. Screw fuses are widely used in various applications, including residential, commercial, and industrial electrical systems.
