I. Overview  
The JSXGN box-type switchgear mechanical interlocking device (hereinafter referred to as the interlock) adopts a mandatory mechanical interlocking method, meeting the requirements of the "five preventions" function, and features simple operation, safety, and reliability. This interlock is suitable for various wiring schemes and structural forms in XGN2-12 box-type fixed metal-enclosed switchgear, and can interlock with electromagnetic operating mechanisms such as CD10 and CD17, as well as spring operating mechanisms such as CT8, CT17, and CT19.
