What does Slow Blow Glass Fuse mean?

Slow Blow Glass Fuse is also called time-delay fuse. Its time-delay characteristics show that it remains intact when the circuit has a non-fault pulse current and can provide protection for long-term overload. In some circuits, the current at the moment of switching is several times larger than the normal operating current. Although the peak value of this current is very high, it appears for a short time. We call it pulse current and also call it inrush current or surge current.
