Description

The Legrand 037167 is a Viking 3 two-level function terminal block in grey with an integrated diode, rated for 4mm² conductors with a 6mm pitch. Providing two connections in a 2-storey configuration with a diode in the circuit path, it is designed for relay coil suppression, signal rectification, and other diode-protected connections within industrial control panels and automation systems. The compact 2-level design maximises terminal density while including built-in diode protection.

The securing pin mechanism ensures accurate Viking 3 block alignment on the DIN rail, and two marking zones per level provide clear circuit identification. The 037167 is part of Legrand’s specialised Viking 3 function terminal block range and is widely used in PLC output, relay, and control circuit panels where diode-protected connections are required as standard practice.
