| 简介 |
PURPOSE : A fusible link is provided to prevent from being melted when overcurrent is flowed at a rare short circuit range. CONSTITUTION : A melting part includes a first resistor(10) and a second resistor(20) which are formed with a fusible metal conductor. A metal chip has a lower melting point than that of the fusible metal. The metal chip is melted to be distributed over a fusible part to form an alloy when the metal chip is heated by the overcurrent. A holding unit(30) is arranged around the fusible part to support the metal chip. |
