Description

The Legrand 037174 is a Viking 3 protective earth terminal block in green/yellow for 16mm² conductors, with a metal base for direct DIN rail earth bonding and a pitch of 12mm. Rated for the highest-current standard earth connections in the Viking 3 PE range, it is used in main distribution panels, industrial switchboards, and motor control centres where large earth conductor cross-sections are required for fault current carrying capacity. The metal base establishes a continuous, low-impedance earth bus throughout the terminal row.

Fully compatible with the Viking 3 system including securing pin alignment, two marking zones for identification, and bridging comb zones, the 037174 integrates seamlessly into comprehensive terminal assemblies. Green/yellow colour coding ensures unambiguous PE identification. It is widely specified for main earth bars, sub-distribution earth terminals, and equipment earth connections in high-power industrial and commercial panel installations.
