FUSE A thin metal strip which burns through when too much current flows through it, thereby stopping current flow and protecting a circuit from damage. FUSIBLE LINK METER, DIGITAL Current flow activates one or many LED’s, LCD’s, or fluorescent displays, which provide a relative or digital display. FUEL FUSIBLE LINK (for Medium Current Fuse) A heavy–gauge wire placed in high amperage circuits which burns through on overloads, thereby protecting the circuit. The numbers indicate the crosssection surface area of the wires. MOTOR A power unit which converts electrical energy into mechanical energy, especially rotary motion. M (for High Current Fuse or Fusible Link)
