Cooper Bussmann 3A F Ceramic Cartridge Fuse, 6.3 x 25mm

This range of fuses from Eaton Bussmann are fast-acting with high rupture capacity. They are suitable for various different uses, providing reliable performance and cost-effective circuit protection. They are ideal for use in plugs to protect cables from melting or catching fire if they are overloaded.

Why choose ceramic cartridge fuse?

Ceramic and glass cartridge fuses have similar properties. The capacity of a ceramic cartridge fuse is higher than other fuses, which means that ceramic fuses can be used in circuits that have a higher current rating. They are perfect for protecting against overheating.

What size is it?

This range of fuses is 6.3 x 25 mm, meaning they are 25mm long and 6.3mm in diameter.

What is HBC?

HBC stands for high breaking current and refers to the maximum current that the fuse can handle without breaking. It is also known as HRC (High Rupturing Capacity).

What Speed is it?

These fuses are “F” speed rated, which is short for Fast Acting. This is also known as fast blow and is popular in general purpose applications. They are designed not to handle current spikes over the rated current.

What voltage is it?

These cartridge fuses are available with 1 to 13 Amp current ratings for applications where the system voltage rating is 240 Volts AC.

What is Breaking Capacity?

Breaking capacity is the level of current that the fuse can safely handle without exploding or breaking. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit.

What are cartridge fuses used for?

• For the protection of components and equipment from costly damage used by over-current
• To isolate sub-systems from the main system once a fault has appeared

What is an overcurrent?

It is a setting where a circuit experiences a current that is higher than the normal operating current.

IEC 269-3A

Use this cartridge fuse from Eaton in an electrical plug to protect your appliance or device from short circuits and overloads. It has a Type F fuse speed, so it acts quickly to prevent damage to equipment and cables caused by overheating and power surges.
The ceramic body has a high breaking capacity (HBC) and a 240V AC voltage rating, which means it's suitable for use with domestic and commercial appliances such as desk lamps, computers and power tools.

• Standard body size of 25 (length) x 6.3mm (diameter) means it's compatible with fuse holders in British plugs
• Corrosion-resistant nickel-plated endcaps for increased durability and conductivity
• Ceramic body is thermally stable and can resist high temperatures
• Red label colour means you can easily identify it, to speed up maintenance and repairs

This fuse has a 3A rating, so it's suitable for electrical plugs on low-power appliances. Before you fit it, you should make sure this rating matches the one marked on your plug.
