Distribution enclosure Legrand RN-65 4x18 modules IP65 surface-mounted model 601948

Legrand RN-65 distribution enclosure model 601948 is a surface-mounted, sealed cabinet designed for installations that require protection against dust and water. Configured to hold up to four rows of 18 modular devices each (4x18), this IP65-rated enclosure provides a sealed housing for circuit breakers, residual-current devices and other modular DIN-rail components in industrial, commercial or residential settings.

Advantages

The enclosure combines a robust, dust- and water-resistant construction with a surface-mounted design that simplifies installation on walls or flat panels. Its modular 4x18 layout allows for organized placement of protection and switching devices while maintaining accessibility for wiring and maintenance. The IP65 rating ensures protection in environments exposed to splashes, dust ingress and routine cleaning, reducing the need for custom sealing or additional protective measures.

Suitable for

• Industrial control panels and machinery requiring sealed distribution cabinets
• Commercial electrical distribution in retail, office or service spaces
• Residential installations where dust- and water-resistance is necessary (laundries, garages, utility rooms)
• Outdoor or semi-outdoor installations when mounted under covers or in sheltered locations
• Retrofit projects replacing non-sealed cabinets with IP65 protection

Key specifications

• Mounting: surface-mounted design for wall or panel attachment
• Module capacity: 4 rows × 18 modules (total layout for modular DIN-rail devices)
• Protection rating: IP65 — dust-tight and protected against water jets/splashes
• Compatibility: accepts DIN-rail mounted modular devices such as circuit breakers and RCDs
• Access: front-opening door for installation and maintenance access

How to use

Mount the enclosure on a suitable flat surface using appropriate fixings for the substrate and load. Install DIN-rail(s) inside the cabinet if not pre-fitted, then snap-fit modular devices (MCBs, RCDs, contactors) on the rails according to the planned electrical layout. Route incoming and outgoing cables through the recommended cable entries or gland plates, ensuring cable seals maintain the IP65 rating. After wiring, close and secure the front door to restore the enclosure’s protective integrity. Ensure adherence to local electrical codes and safety practices throughout installation and commissioning.

Usage recommendations

For sustained IP65 performance, use compatible cable glands or sealed entries and avoid making unnecessary penetrations. Place the enclosure under a small canopy for outdoor use to reduce direct exposure to driving rain, and perform periodic inspections of seals and gaskets to maintain dust- and water-resistance.
