Commercial office desk power outlets must be individually fused as per BS 6396 office furniture installation standard. Typically these outlet use the small 20mm fuses, which is shorter and smaller than the 25mm-long fuses widely used in wall sockets and electric appliances and devices. The diameter of the fuse is 5mm (vs 6.3mm of normal ones).
The Ø5x20mm cartridge fuses are also popular in electric board and panel protection.
1. What is Speed T fuse, what is the difference with the Speed F fuse? ?
Speed T fuses are slow acting fuses, 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. Speed F fuses are designed to protect less sensitive components and are also used to protect 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.
2. 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 LBC (Low Breaking Capacity).
