Patent number: 10468861Abstract: Provided is a distribution panel. The distribution panel includes a main busbar compartment in which a main busbar is provided and which is provided as an independent space and an arc duct provided at a rear side of the main busbar compartment to discharge an arc generated in the main busbar compartment. The main busbar compartment includes a communication hole defied in one surface of the main busbar to allow the main busbar compartment to communicate with the arc duct and a relief device rotatably provided on one side of the communication hole to open or close the communication hole. The relief device is bendable in multi stages. Thus, the arc may be effectively discharged while reducing a size of the distribution panel.Type: GrantFiled: December 18, 2018Date of Patent: November 5, 2019Assignee: LSIS CO., LTD.Inventors: Seog Won Lee, Ji Hoon Ma, Jong Doo Kim, Seung Hwan Mun
