Product information

Description

The Legrand 400408 Modular Distribution Block 125A 4-Pole 6-Module is a professional electrical accessory designed to provide organized and secure power distribution within industrial and commercial electrical panels. Built to meet standard electrical installation requirements, this 4-pole distribution block handles up to 125A of current and occupies 6 modules of space on a standard DIN rail. Supplied in a practical pack of 6 pieces, it helps streamline wiring layouts and ensures reliable electrical connections for complex distribution setups.

Advantages

This modular distribution block facilitates clean and structured cable management inside electrical enclosures, reducing installation time and minimizing the risk of wiring errors. Its robust construction supports demanding electrical environments, ensuring long-term operational reliability and safety in professional power distribution systems. The standardized 6-module width allows for seamless integration into existing modular enclosures without requiring complex modifications.

Suitable for

  • Industrial electrical control panels and automation systems
  • Commercial building power distribution boards
  • Professional electrical installations requiring secure 4-pole routing
  • Upgrading or expanding existing modular electrical enclosures

When it may not be suitable

This distribution block is not intended for residential consumer units where lower current ratings or fewer poles are typically required. It is also unsuitable for outdoor installations without an appropriate weatherproof enclosure, as it is designed exclusively for indoor panel mounting.

Key specifications

  • 4-pole configuration
  • 125A current rating
  • 6-module width
  • Pack quantity of 6 pieces
  • Dimensions: 112 mm width, 108 mm height
  • Weight: 2 kg

How to use

Mount the modular distribution block securely onto a standard DIN rail inside a compatible electrical enclosure. Ensure the main power supply is completely switched off before attempting any wiring work. Connect the incoming and outgoing cables to the appropriate terminals, and tighten all connection screws securely to the recommended torque specifications to prevent loose contacts. Verify all connections for correctness and security before restoring power to the system.

What to consider before purchase

  • Verify that the 125A current rating matches your electrical system requirements
  • Ensure your enclosure has at least 6 modules of available DIN rail space
  • Confirm that a 4-pole configuration aligns with your distribution setup
  • Check the pack quantity to ensure it meets your installation scale
Usage recommendations: Installation should be performed strictly by qualified electrical professionals in compliance with local electrical safety regulations and wiring standards. Regularly inspect connections during routine maintenance checks.

Product comparison

Electrical distribution blocks and enclosures are essential for organizing safe power distribution within electrical panels and switchboards. Legrand Modular Distribution Block 4-Pole 125A 400408 is compared with two alternative products: NORDEL NLDB125A Distribution Block 125A 1000V for Aluminum and Copper Conductors and Legrand Practibox S surface-mounted modular enclosure 1x22 modules IP40 transparent door with 1P B16 RX3 circuit breaker. While all these items belong to electrical installations, they serve different purposes: the Legrand 400408 modular block manages 4-pole power distribution at 125A, the NORDEL block handles aluminum and copper conductors with specific input and output configurations, and the Practibox S set provides a surface-mounted enclosure with IP40 protection and a pre-included circuit breaker for comprehensive circuit protection.

⚙️ The specifications comparison covers device type, structural design, electrical ratings, and intended application to highlight their technical differences.
