Anti Surge (T) HBC – Ceramic Bodied, 5 x 20
Anti-surge ceramic cartridge fuses 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
Why choose a glass fuse?
Glass and ceramic fuses have similar properties. However you may choose a glass 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?
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 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).
