What is a Fast acting fuse?
Fast acting fuse, also known as quick break fuse, quickly disconnects the current in the event of overcurrent or short circuit. Its characteristic is the ability to quickly respond to overcurrent situations, thereby protecting sensitive electronic components and circuits from damage.
The working principle of a fast fuse is to use a fuse, also known as a fusible element, which will melt when the current exceeds its rated capacity. A fuse element will cut off the circuit, prevent current from flowing, and prevent damage to circuit components. The response speed of a fuse is related to the current and the duration of the current, usually described by the I ² T characteristic, where “I” represents the current and “T” represents time. The higher the current, the faster the fuse will melt. This fast response characteristic is used when the surge current is small or requires immediate interruption to protect other components of the circuit.
