Terminal block Legrand 004834 — DIN-rail electrical connector, compact modular terminal

Legrand 004834 is a compact modular terminal block for DIN-rail mounting, designed for secure earthing connections in electrical distribution and control panels. Supplied ready for use with screws not tightened, this connector complies with IEC 60998-2-1 and is intended for installations where reliable protective earth continuity is required. The terminal block is finished in green and offers multiple conductor accommodation options within a slim, space-saving length of 113 mm.

Advantages

This terminal block supports both large and small conductors, enabling a single device to accept one main conductor alongside multiple smaller connections. It is rated for high currents up to 100 A (with 25 mm² conductors) and 80 A (with 16 mm² conductors) at 400 V~, providing robust performance for protective earth circuits. The unit is supplied ready for mounting on a DIN rail or on a 12 x 2 mm flat bar using the universal support, which simplifies panel assembly and replacement. The compact modular design reduces panel space usage while maintaining clear, reliable terminations.

Suitable for

• Earthing connections in distribution and control panels
• Industrial, commercial and residential electrical installations
• Panels requiring mixed conductor sizes (single large conductor plus multiple smaller conductors)
• DIN-rail or flat-bar mounted grounding systems

Key specifications

• Standards: Conforms to IEC 60998-2-1
• Electrical rating: 100 A max at 400 V~ (with 25 mm² conductor); 80 A max at 400 V~ (with 16 mm² conductor)
• Conductor capacity: 1 × 6 to 25 mm² plus 12 × 1.5 to 16 mm²
• Color: green (earth)
• Mounting: DIN-rail with universal support or on 12 × 2 mm flat bar
• Length: 113 mm

How to use

Mount the terminal block on a standard DIN rail using the specified universal support or secure it on a 12 × 2 mm flat bar. Insert the conductors into the designated clamps: a single large conductor into the main input and the smaller conductors into the multiple auxiliary positions. Tighten the screws to the recommended torque for the conductor cross-sections; the product is supplied with screws not tightened. Ensure protective earth continuity and verify connections with suitable testing equipment before energizing the circuit.

Usage recommendations

Use appropriate conductor ferrules or end sleeves for stranded conductors to improve contact reliability and prevent strand splaying. Respect the maximum current and conductor size ratings and follow national wiring regulations and safety practices when installing earthing terminals.
