## Description

BOJACK 20 Pcs High Quality Slow-blow Glass Fuse Fuse model:T6.3AL250V Fuse Current: 6.3A Fuse Voltage: 250V Fuse Dimension:5x20mm/0.2x0.78 Inch The role of the Slow-blow fuse：The slow-blow fuse is also called a time-delay fuse. Its delay characteristic is maintained in the circuit when it has a non-fault pulse current and can protect against long-term overload. Some circuits have a current greater than a few times the 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 larger fuse 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.

Review: Nice product for the price - I recently purchased these fuses as I like to fix electronics. The pack came with various options and sizes that were extremely handy. My primary use was for my guitar amp and boiler, and they've worked like a charm, keeping my devices running smoothly without any hiccups. These fuses are excellent value as they compare well against other options like Screwfix or B&Q. I like the plastic box as it organises them neatly, much better than a zip-lock bag. However, as good as they are, I would say the size can sometimes be misleading - one or two fuses did fit somewhat snugly but eventually went in just fine. All in all, this hasn’t been a deal breaker for me. I’d recommend these to anyone who dabbles with home electronics or needs a quick, reliable fix for their appliances. Good quality and definitely worth the purchase!
Review: Good alternative. - Just the right ones needed and none blown yet after all this time. Would definitely buy again.
