## Description

BOJACK 20 Pcs High Quality Slow-blow Ceramic Fuses Fuse model:T6.3AL250V Fuse Current: 6.3A Fuse Voltage: 250V Fuse Dimension:5x20mm/0.2x 0.78 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. Although this 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 circuit uses 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 absorb energy. By adjusting the energy absorption, it can resist the inrush current and protect the overload.

Review: Worked great for my powered speaker! - I have Behringer powered speakers and one of them started going out (at very inopportune times!). I tested the other speaker's fuse and it started working again so I knew it was a fuse that blew. These fuses worked perfectly and look exactly like the original!
Review: Worth the wait - These fuses are impossible to find locally. If you can wait for there delivery then save yourself the hassle of looking locally. They work great and are very inexpensive.
