Miniature cylindrical glass fuse link 5X20 T 20A/250V 006710057

5x20 T glass cylindrical miniature fuse 20A/250V

The 5x20 T glass cylindrical miniature fuse is a component for protecting electrical installations with a rated current of 20A and a voltage of 250V. Made using glass technology, it allows for visual monitoring of its safety status.

Construction and technical characteristics

The product belongs to the Ultra-Quick series, featuring a fast response to overloads and short circuits. Compact dimensions (length 20mm, diameter 7.2mm) allow for installation in standard 5x20 fuse holders. The glass body enables immediate visual inspection of the fuse status—a blown fuse is visible to the naked eye without the need for disassembly.

A net weight of 1.92g makes the product practical for daily operation, while precise manufacturing ensures consistent operating parameters across the entire production series.

Application and compatibility

The fuse is used for protecting electronic circuits, measuring devices, and control installations. The transparent body allows for status monitoring without the need to disconnect the power supply, which is particularly useful during frequent servicing.

The product is compatible with all standard 5x20mm fuse holders and bases, facilitating the replacement and maintenance process of the installation.

Advantages and safety

The glass construction eliminates the risk of hidden faults—a blown fuse is immediately visible, which accelerates fault diagnosis. The T type time-current characteristic provides protection against overloads while maintaining resistance to short-term inrush current spikes.

The product meets European standards for electrical safety and can be used in both domestic and industrial installations with a rated voltage of up to 250V.
