The CYDLG4(I.S) is a double-level ground terminal block designed for efficient grounding in industrial and control panel applications. Both the top and bottom levels are internally connected via a built-in link, ensuring consistent electrical continuity across the block and providing a single, unified grounding point. The terminal block is also equipped with a channel clamp that functions as a grounding foot, delivering a secure and reliable connection to the grounding system. The CYDL4 is the corresponding same-profile feedthrough terminal block for use alongside the CYDLG4(I.S).
