Eaton 4A F Glass Cartridge Fuse, 5 x 20mm, Предохранитель

Eaton Bussmann Quick Acting (F) LBC Cartridge Fuses - Glass Bodied, 5 x 20 mm

This range of cylindrical cartridge fuses from Eaton Bussmann is designed to International (IEC) Standards for use globally. It is available in cartridge and axial lead form. They are ideal for providing protection to devices or internal circuits from short circuits and overcurrent. They are deliberately weaker components which, when too much current is drawn, will blow. Once the fuse has blown it will need replacing in order to make the circuit complete and allow the flow of current.

Why choose a glass cartridge fuse?

Glass and ceramic fuses have similar properties. However, you may choose a glass cartridge fuse as it enables you to see the inside of the fuse. Therefore it is easier to determine whether the fuse has blown.

What size is it?

5 mm x 20 mm is a standard cartridge size and it measures approximately 20 mm long by 5 mm in diameter. They are popular in board and panel protection and will fit a compatible 5 x 20 mm fuse holder.

What Speed is it?

This particular fuse is type ''F'' speed-rated which means a fast-acting fuse. These are designed to protect less sensitive components and are also used to protect the cabling from melting or catching fire when an overload appear. Every fast-acting fuse will have the exact speed stated which will be relevant to different overloads.

What voltage is it?

These cartridge fuses are available with 40 mA to 10 Amp current ratings for applications where the system voltage rating is 250 Volts AC.

What is an over-current?

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

What is Breaking Capacity?

Breaking capacity is the level of current that the fuse can safely handle without exploding or rupturing. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit. This particular cartridge fuse is LBC (Low Breaking Capacity).

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

Eaton Glass Cartridge Fuse, 5mm Diameter, 4A - - BK1/S500-4-R

Need a fast-acting protective device for your internal circuits and electronic appliances? Try this general-purpose cartridge fuse from the Eaton range. The component's body is made of glass, so it's easy to see when it's blown and the filament has melted. As it has brass contact end caps, you can be sure of a reliable connection. The contacts themselves are nickel-plated for corrosion resistance, so they won't decay due to rust. An F speed rating indicates this fast-acting fuse responds to the slightest voltage surge. This makes it especially useful in low-voltage applications such as laptops and connectors.

Features & Benefits

• Low breaking capacity of 40A to protect low-power appliances
• Compact dimensions of 5 (diameter) x 20mm (length) to fit into small enclosures
• Low resistance of 21mΩ for high current flow

How does this cartridge fuse work?

This cartridge fuse has a small piece of wire inside that melts when a surge of overcurrent flows through it. This breaks the circuit, stopping the flow of electricity and preventing damage.

How do I install this fuse?

This fuse is easy to install. Simply clip its end caps into the device's carrier or fuse holder and it's ready for use.
