See our video on ground terminal blocks here.

Spring clamp earth terminals have the same outer dimensions as the standart PYK blocks for the same cross-sections. This enables earth terminal blocks to be mounted directly beside feed-through terminal blocks.

The main characteristics are:

• Low transition resistance
• Non-corrosing contacts
• Green/yellow marking on the insulation.

The main difference between spring clamp earth terminals and the earth terminals with screw connections  is the immediate contact when the terminal blocks are attached to the mounting rails.
