Legrand modular lamp L333 3-phase 250–500 V (model 003143)

Legrand L333 modular lamp is a 3-phase lighting module designed for installation in compatible modular electrical systems. Rated for operation at 250–500 V, this compact lamp module integrates into three-phase distribution circuits and is intended for commercial or industrial modular lighting applications. The unit provides a replaceable lighting element for retrofitting existing modular lines or expanding lighting layouts without altering primary distribution equipment.

Advantages

The modular design allows tool-free replacement in systems that accept Legrand-compatible modules, reducing downtime during maintenance. Wide nominal voltage compatibility (250–500 V) supports varied three-phase installations, while the compact format saves space in modular housings. Built to fit standardized modular rails, the lamp offers straightforward mechanical and electrical integration with other modular components.

Suitable for

• Three-phase lighting circuits in commercial buildings
• Industrial production lines and workshops
• Modular electrical distribution boards and retrofit projects
• Areas requiring quick replacement of lighting modules

Key specifications

• Operating voltage range: 250–500 V (three-phase)
• Modular form factor compatible with Legrand-style modular systems
• Designed for installation in modular distribution or lighting rails
• Compact dimensions suitable for space-constrained modular enclosures
• Intended for commercial and industrial environments

How to use

Ensure power to the distribution circuit is switched off and verified before installation. Insert the modular lamp into a compatible module slot or rail until it engages securely according to the host system’s mechanical guidance. Connect the lamp to the three-phase supply following the system’s wiring scheme and local electrical regulations. After installation, restore power and verify correct operation; if illumination does not occur, switch power off again and check electrical connections and compatibility with the host modular system.

Usage recommendations

Use this module only in systems specified to accept Legrand-compatible modular components and in circuits that match the 250–500 V three-phase range. Follow local electrical codes and, when in doubt, consult a qualified electrician for installation and verification. Avoid exposure to environments outside the intended commercial or industrial use to maintain safe operation and product longevity.
