End plates for FRK Push In terminals

End plates are usually inserted at the end of a rail of terminals or when a smaller terminal is used next to a larger one.
This ensures contact protection and the safety of fingers.
The outer dimensions of the end plates correspond to the dimensions of the terminal blocks.
Coloured end plates are often used to mark different power circuits or a change in voltage.
The use of end plates lengthens the airways and leakage paths, which in turn influences the rated voltage.
