(Selection Guide) — How to Select the Right Fuse for Power Systems Protection
“A fuse is essentially a metal wire or strip that heats up and melts when too much current flows through it, thereby opening the circuit and interrupting the current flow.”
In order to select the right fuse for a given system, it is imperative that the various fuse parameters are thoroughly understood. Hence, this guide will first define each contributing factor and then explain how it is used by engineers and circuit designers to choose the best device for circuit protection.
We just launched our Power Systems Engineering Vlog series and in this series, we are going to talk about all sorts of various power system engineering studies and commentary. We will overview the different blogs written by AllumiaX. It’s fun, it’s lively, it’s a video blog essentially and we hope that you’ll join us and benefit from it.
The following factors should be considered when selecting a fuse for a given system:
- Normal operating current
- Operating Voltage
- Ambient Temperature
- Inrush Currents
- Maximum Fault Current
- Length of time in which the fuse must open
Maximum allowable I²t
