WebAug 27, 2024 · 1), For motor circuit, if the fuse is used in main circuit, we should consider the fuse rated current is at least 1.6 times of main circuit operation current. Voltage, same or higher than circuit operation rated voltage is OK. If fuse is used in auxiliary loop (Also called the control loop), it will need the independent design. In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current. It is a sacrificial device; once a fuse has operated it is an open circuit, and must be replaced or rewired, depending on its type.
