Fuses

Fuses are used as a sacrificial device to protect expensive electrical components from any damaging effects of electric currents. They operate by providing overcurrent protection of an electrical circuit by utilizing a metal wire or strip that melts when too much current flows through it. This process would then stop the current from flowing through the circuit. Shop our range of fuses right here at Jackson Systems & Supply.
