BOJACK 20 Pcs High Quality Slow-blow Ceramic FusesFuse model:T6.3AL250VFuse Current: 6.3AFuse Voltage: 250VFuse Dimension:5x20mm/0.2x 0.78 InchThe role of the Slow-blow fuse:The slow-blow fuse is also called atime-delay fuse. Its delay characteristic is maintained in the circuitwhen it has a non-fault pulse current and can protect against long-termoverload. Some circuits have a current greater than a few timesthe normal operating current at the switching instant. Althoughthis current peak is very high, it occurs for a short period of time.We call it a pulse current or an inrush current or a surge current.Ordinary fuses can not withstand such currents. If such a circuituses an ordinary fuse, it may not be able to start normally. If a largerfuse is used, it will not be protected when the circuit is overloaded.The melt of the time-delay fuse is specially processed to absorbenergy. By adjusting the energy absorption, it can resist the inrushcurrent and protect the overload.
