23 Amp Midi Fuse

A fuse protects electrical appliances and equipment by breaking the electrical circuit in the event of an overload of current or a short circuit. When a fault occurs, such as an overload or short circuit, the high current that is flowing through the fuse melts the fuse element, thus interrupting the flow of current and breaking the circuit. This prevents the appliance from damage due to excess current.

Each fuse responds differently to current flow and surges, and takes a different amount of time to react; it is therefore important to choose the correct fuse for the circuit it is to be introduced in. An incorrect fuse could either mean no protection because it has not melted in time, or over sensitivity when it blows repeatedly for no real reason.
