Ground Terminal Blocks
A ground terminal block is a DIN rail terminal block, recognizable by its yellow-green housing, that electrically connects the protective conductor (PE) to the mounting rail through its metal foot. It is used in control and distribution panels to terminate the protective conductors of field cables within the terminal block row, next to the phase and neutral terminal blocks. In this category, Onka MTK series screw-connection ground terminal blocks are sold per piece in 2.5 mm², 4 mm², 6 mm², 10 mm², 16 mm², 25 mm² and 35 mm² cross-sections with a 750 V voltage rating. Choose the terminal block by the cross-section of the protective conductor you will connect, and by the series and housing height of the feed-through terminal blocks that will be lined up on the same rail; at 35 mm² cross-section, the standard and tall housings are separate products. The product standard for protective conductor DIN rail terminal blocks is IEC 60947-7-2. A ground terminal block should not be confused with the multi-hole busbar-type panel ground terminal block: a panel ground terminal block is not lined up one by one in the terminal block row, it collects the protective conductors in the panel on a single busbar.

How to choose Ground Terminal Blocks
A ground terminal block is a DIN rail terminal block, recognizable by its yellow-green housing, that electrically connects the protective conductor (PE) to the mounting rail through its metal foot. It is used in control and distribution panels to terminate the protective conductors of field cables within the terminal block row, next to the phase and neutral terminal blocks.
- Clarify whether the task is connection, cable routing, enclosure distribution or termination.
- Match dimensions, thread standard, conductor cross-section and IP rating with the cable and panel.
- Choose housing material and pack quantity according to the mounting environment.
