Modular Surface-Mounted Distribution Box ELEKTROPLAST RH-54/3 3x18 modules, hermetic

The ELEKTROPLAST RH-54/3 modular surface-mounted distribution box is a hermetic enclosure designed to accommodate DIN-rail mounted electrical modules in three rows of 18 modules each. Intended for installations that require a sealed housing, this distribution box protects circuit breakers, RCDs and control modules from dust and moisture while enabling tidy surface-mounted wiring. The box is suitable for residential, commercial and light industrial settings where a compact, modular distribution solution is needed.

Advantages

The hermetic design reduces the ingress of dust and water, extending the operational reliability of installed electrical components. The three-row layout allows clear separation of circuits and simplifies expansion or rearrangement of modules. Surface-mount installation avoids the need for recessed wall cavities and facilitates retrofit or new installations. The enclosure offers visible organization for DIN-rail devices and supports standard modular components typically used for circuit protection and control.

Suitable for

• Surface-mounted residential electrical distribution with multiple consumer units
• Commercial premises requiring a sealed distribution enclosure
• Light industrial applications where protection against dust and splash is needed
• Retrofit installations where recessed mounting is not possible
• Panels housing breakers, RCDs, contactors and auxiliary modules

Key specifications

• Mounting type: surface-mounted enclosure
• Module capacity: 3 rows × 18 modules per row
• Enclosure protection: hermetic design for reduced dust and moisture ingress
• DIN-rail compatibility: accepts standard DIN-rail mounted modular devices
• Typical applications: breakers, residual current devices, control and auxiliary modules

How to use

Install the distribution box on a flat surface using appropriate fasteners for the wall material, ensuring the enclosure is mounted level and at a suitable working height. Fit DIN rails and mount modular devices such as circuit breakers and RCDs according to the modules’ installation instructions and local electrical regulations. Route incoming and outgoing cables through provided cable entries or knockouts, maintain correct conductor separation and secure all connections. After wiring and testing, close the enclosure to maintain the hermetic protection.

Usage recommendations

Ensure installation and any modifications are performed by a qualified electrician in accordance with applicable standards and local regulations. Use compatible DIN-rail components sized for the enclosure’s module spacing and observe recommended torque values for terminal connections to maintain safe operation and the enclosure’s protective properties.
