Multipolar fusible link

A multipolar fusible link comprising:

• an input terminal;
• a bus bar through which an electric current input from the input terminal flows;
• and
• fusible sections positioned between and connected to the bus bar and a plurality of terminals such that the plurality of terminals are connected to the bus bar via the fusible sections, wherein:
• a lower edge of the bus bar to which the fusible sections are connected varies such that a width between the lower edge of the bus bar and an upper edge of the bus bar positioned opposite the lower edge is gradually decreased from a portion to which the fusible section closest to the input terminal is connected towards the end edge opposite to the input terminal in an axial direction along a length of the bus bar, and
• lengths of the fusible sections vary in an inverse relationship to the widths of the portions of the bus bar to which the fusible sections are connected,
• wherein, as the bus bar linearly extends in the axial direction, the width of the fusible section decreases, the decrease of the width varies in proportion to the width between the lower edge of the bus bar and the upper edge of the bus bar in the axial direction of the bus bar.
