5x20mm Glass Cartridge Axial Lead Fuse Resistor Insurance Tube Fusible Cutout with Lead Wire 6.3AMP1

A cartridge type fuse is a type of electrical fuse that is commonly used in residential, commercial, and industrial buildings to protect electrical circuits and appliances from overcurrent and short circuit conditions.

Glass cartridge fuse consists of a cylindrical shaped body with metallic caps on both ends. Inside the current fuse body, there is a fusible link or wire that melts when the current exceeds its rated capacity, thereby breaking the circuit and preventing damage to the electrical system.

Cartridge fuses are available in different sizes and ratings, depending on the requirements of the electrical circuit. They are easy to install and replace, and provide a high level of protection against electrical faults.

There are two types of cartridge fuses:

1. D-type cartridge fuse: This type of fuse has a built-in rejection feature that prevents the insertion of a fuse with a higher voltage or current rating than the circuit can handle.

2. Link-type cartridge fuse: This type of fuse does not have a rejection feature and can be replaced with any fuse that fits the holder, regardless of its voltage or current rating.

Cartridge fuses are commonly used in electrical appliances, HVAC systems, power tools, and other electrical devices.
