Surface-Mounted Hermetic Distribution Box Legrand RN65 72-Module (LE-601948)

Legrand RN65 surface-mounted hermetic distribution box is a sealed enclosure designed to house up to 72 modular devices on DIN rails. The LE-601948 model offers a compact, dust- and moisture-resistant solution for organizing circuit breakers, residual current devices (RCDs) and other modular electrical components in residential, commercial or light industrial settings. The robust housing and gasketed door provide protection where a surface-mounted, weather-protected installation is required, while internal mounting rails and knockouts help streamline wiring and component placement.

Advantages

This hermetic distribution box combines a high module capacity with a sealed design to reduce the risk of dust ingress and moisture exposure. The surface-mounted format simplifies installation on walls or panels without the need for recessed mounting. The enclosure provides clear access to modular devices through a hinged, gasketed door and allows orderly arrangement of circuit protection and control components on DIN rails. Materials and construction are chosen to balance durability and ease of installation for indoor and sheltered outdoor installations.

Suitable for

• Housing multiple DIN-rail modular devices such as circuit breakers and RCDs
• Surface-mounted electrical distribution in apartments, offices and small commercial premises
• Protected installations where dust and occasional moisture exposure are a concern
• Retrofit projects requiring a non-recessed distribution enclosure

Key specifications

• Module capacity: up to 72 modular devices
• Mounting type: surface-mounted enclosure with DIN rails
• Enclosure protection: hermetic/sealed design to limit dust and moisture ingress
• Access: hinged front door with gasket for a sealed closure
• Installation environment: indoor or sheltered outdoor locations
• Internal features: pre-fitted DIN rails and wiring knockouts for cable entry

How to use

Install the enclosure on a suitable flat surface using the designated mounting points and appropriate fixings for the substrate. Open the hinged door and mount modular devices onto the internal DIN rails in the required arrangement, observing manufacturer instructions for each device and ensuring correct spacing and labelling. Route incoming and outgoing cables through the allocated knockouts, apply suitable cable glands or seals for maintaining the hermetic integrity, and terminate conductors following applicable wiring regulations. Close the gasketed door and verify that the enclosure maintains the intended seal.

Usage recommendations

Use the distribution box in environments that benefit from a surface-mounted, sealed enclosure; avoid prolonged direct exposure to heavy rain or immersion. Select compatible DIN-rail modules sized for the 72-module capacity, and use appropriate cable glands or seals at all entry points to preserve the hermetic properties.
