RS PRO Anti Surge (T) HBC - Ceramic Bodied, 5x20 RS PRO anti-surge ceramic cartridge fuses which are designed to prevent damage to electrical equipment. These fuses allow an electric current to flow through until the current goes over the fuses rating then it will blow and stop the flow of electricity. This range of ceramic cartridge fuses are 5 x 20mm with a T speed rating.
RS PRO cartridge fuse packs are available in a range of current ratings with varying resistance values to suit all your requirements. This range is reliable for a broad range of applications.

Features:
Ceramic cartridge
T Speed rated
5mm x 20mm cartridge size

Typical applications:
Cartridge fuses are a relatively cheap way of protecting electrical equipment from short circuits and overcurrent and can be used to protect electrical appliances such as motors air-conditions, refrigerator, pumps etc. They can be found in the following areas:
Industrial
Commercial
Home/Residential
Automotive

Additional Information

What size is it?
5x20 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 5x20 fuse holder.

What Speed is it?
This particular fuse is “T” speed rated which means it is a slow acting fuse, sometimes referred to as anti-surge. It is able to tolerate higher levels for a short period, without shorting. Therefore, if a sudden change occurs, this fuse will not blow immediately. They are suitable for applications where a sudden flow of high current is required.

What are fuses used for?
• For the protection of components and equipment from costly damage caused by over-current.
• To isolate sub-systems from the main system once a fault has appeared

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 fuse is HBC (High Breaking Capacity).
