Glass Tube Fuse

A glass tube fuse is a protective device utilized to prevent electrical circuits from damage owing to over-current. Constructed from glass and metal, it features a high insulation resistance and operates at a maximum voltage of 250V. Its design comprises a glass tube housing a metal wire or filament that melts to interrupt the circuit during over-current conditions. Standard protection level makes it suitable for varied consumer electronics and household appliances. Key components comprise the glass tube, metal filament, and end caps. Manufacturing involves precision in glass blowing and metal welding. Maintenance requires periodic checks for continuity, and replacement should be timely to guarantee effective protection.
