The CYDLF4L6-60V is a double-level fuse terminal block with a fuse function on the top level and a feedthrough function on the bottom level, combining two functions into a single compact unit and reducing the need for separate terminal blocks, saving up to 50% of DIN-rail space. An integrated LED indication system provides immediate visual feedback when a fuse is blown, significantly reducing troubleshooting time. Both levels include jumpering provisions for flexible power distribution and simplified wiring. The CYDLF4FT is the corresponding feedthrough variant, sharing the same profile for a consistent panel layout. These terminal blocks offer an effective solution for streamlining wiring in DCS and process automation systems, enhancing both efficiency and modularity in control panel design.
