Terminal block Legrand 004842 – DIN-rail electrical connector, compact module (package 442 g, 101×89 mm)

Legrand 004842 is a neutral terminal block designed for DIN-rail mounting to provide safe and compact electrical connections in control panels, distribution boards and industrial installations. The module is supplied ready for use with screws not tightened and is intended to conform to IEC 60998-2-1 standards. Its compact dimensions and blue colour identify it as a neutral conductor terminal while supporting multiple conductor sizes for common wiring needs.

Advantages

The terminal block supports a wide range of conductor cross-sections, enabling flexible wiring from small control conductors to larger power feeds. It is rated for high current capacity when correctly sized to the conductor: up to 100 A with 25 mm² and up to 80 A with 16 mm² conductors at 400 V~, providing robust performance in distribution and control circuits. The product’s DIN-rail mounting and compatibility with universal support or a flat bar facilitate straightforward installation and integration into standard electrical panels.

Suitable for

• Neutral wiring in industrial and commercial distribution boards
• Control panel terminations and internal wiring
• Electrical installations that require IEC 60998-2-1 conformity
• Applications needing a compact DIN-rail terminal with multiple connection points

How to use

Mount the terminal block onto the DIN rail using the specified universal support or attach it to a 12 x 2 mm flat bar. Insert stripped conductor ends into the corresponding connection points and tighten the screws to the required torque (screws supplied but initially not tightened). Ensure conductors match the terminal’s rated cross-section and that the installation is carried out with power switched off. Verify tightness and electrical continuity before re-energising the circuit.

Usage recommendations

Use the terminal for neutral bus wiring and group neutral connections. Select conductor cross-sections according to the current and voltage ratings indicated (100 A with 25 mm², 80 A with 16 mm²) and maintain proper torque on screw connections to avoid heating. Keep wiring practices compliant with applicable local electrical codes and perform routine inspections for mechanical tightness and corrosion.
