HL24P03 24-Module Pre-Wired 3-Phase Distribution Board SPD 40A 30mA RCD IP30

The HL24P03 is a factory pre-wired and tested 24-module distribution board with integrated surge protection, supplied ready to connect. It pairs a Hager Volta two-row flush IP30 enclosure with Legrand RX³ protection and a Legrand Type 1+2 surge protective device (SPD): a 4-pole 40A 30mA Type A RCD feeding one three-pole and five single-pole B16 circuits, with the SPD guarding the installation against lightning and switching surges. Built for three-phase 230/400V installations in homes, apartments and light commercial premises, it arrives fully wired with busbar, neutral and earth bars done, leaving 8 spare ways for future circuits.

Technical specifications

• Part number: HL24P03

Features and benefits

• Factory pre-wired and tested: no internal assembly, busbar cutting or comb wiring on site
• Type 1+2 SPD diverts lightning and switching surges at the service entrance, protecting downstream equipment
• Type A RCD trips on both AC and pulsating DC residual currents, covering circuits with electronic loads that a Type AC device would miss
• 30 mA sensitivity adds protection against electric shock
• B16 curve breakers suit general lighting and socket circuits with low inrush
• 8 spare module ways for adding circuits later
• Flush enclosure finishes level with the wall surface
• Branded protection throughout: Hager Volta enclosure, Legrand RX³ devices

Applications

• New three-phase consumer units in houses and apartments
• Renovation and rewiring projects
• Light commercial and office sub-distribution
• Replacement of older fuse boards
• Installations needing surge protection, such as rural or overhead supplies and sites with sensitive electronics

Built from components compliant with IEC 61008-1 (RCD), IEC 61643-11 (SPD) and IEC 60898-1 (MCBs); enclosure to DIN 43870, IP30 per IEC 60529.
