Modular Electrical Distribution Board Legrand RWN 602434P flush-mounted 4x12 modules IP40 white full door with 1P B16 RX3 MCB (4 pcs)

Flush-mounted modular distribution board Legrand RWN 602434P is designed to accommodate up to four rows of 12 DIN modules (4x12) in a compact, recessed enclosure. The unit features an IP40-rated body and a white full door that conceals wiring and modules for a tidy installation. The board is supplied with four 1-pole B16 RX3 miniature circuit breakers (MCBs) to provide immediate basic overload and short-circuit protection for several lighting or power circuits in residential and light commercial settings.

Advantages

The enclosure's flush-mounted design allows it to sit level with the wall surface for a discreet finish, while the full door protects internal components from dust and accidental contact. The IP40 rating ensures protection against solid objects larger than 1 mm, suitable for indoor installations. Pre-fitted single-pole B16 RX3 breakers simplify initial setup and reduce the need for additional components at installation. The internal layout supports organised wiring and expansion with standard DIN-modular devices.

Suitable for

• Residential electrical distribution for apartments and single-family homes
• Small commercial premises and offices with multiple lighting and power circuits
• Renovation projects requiring a recessed distribution board for a neat interior finish
• Installations where basic circuit protection and modular expansion are needed

How to use

Install the distribution board into a prepared wall recess at a height and location compliant with local electrical codes. Secure the enclosure to the structural opening and connect the incoming supply conductors to the appropriate busbar or main terminal inside the board. Fit required additional DIN devices into the free module spaces and terminate outgoing circuit conductors to the respective breaker terminals. Verify correct polarity, tighten terminals to specified torque, and restore supply to test each circuit. Commissioning and final connections should be performed by a qualified electrician in accordance with applicable standards.

Usage recommendations

For safe and reliable operation, use appropriately rated conductors and protective devices when expanding or modifying circuits. Maintain accessible clearances around the enclosure, avoid installing in damp or exposed outdoor locations due to the IP40 rating, and have periodic inspections performed by a qualified professional.
