Modular surface-mounted distribution box ELEKTROPLAST RNT 4S 1x4 IP42 model 3.2

ELEKTROPLAST RNT 4S 1x4 IP42 model 3.2 is a modular surface-mounted distribution box intended to accommodate up to four DIN-module positions in a single row. The enclosure is designed for surface installation and provides IP42 protection against ingress of solid objects and vertical water drops. It is suitable for organizing miniature circuit breakers, residual current devices and terminal blocks in residential and light commercial electrical installations.

Advantages

The enclosure offers a compact, space-saving layout that simplifies wiring and component placement. Its surface-mount design enables easy installation without the need for recessed mounting, and the IP42 rating ensures basic protection for internal components against dust and dripping water. The modular single-row format supports standard DIN modules for flexible configuration and straightforward maintenance.

Suitable for

• Small residential distribution panels and apartment breaker arrangements
• Light commercial or service premises with indoor electrical installations
• Housing of MCBs, RCDs and small terminal blocks in a single-row configuration
• Retrofit projects where surface-mounted enclosures are required

Key specifications

• Module positions: 1 row × up to 4 DIN-module spaces
• Mounting type: surface-mounted enclosure
• Protection class: IP42 (protection against solid objects >1 mm and vertical water drops)
• Intended use: indoor electrical distribution and protection devices
• Compatibility: accepts standard DIN-rail mounted modular devices

How to use

Mount the distribution box on a flat vertical surface using appropriate fasteners for the substrate. Install a suitable length of DIN rail if not pre-fitted, then mount modular devices such as MCBs and RCDs onto the rail according to their manufacturer's instructions and local wiring regulations. Route and secure conductors through the enclosure knockouts or entry points, observing clearances and maintaining separation between live parts. Close the cover and secure it to protect installed components. Ensure the installation is completed and tested by a qualified electrician.

Usage recommendations

Use this surface-mounted distribution box for indoor installations where a compact single-row arrangement is sufficient. Avoid outdoor exposure and environments with high humidity or direct water jets; comply with local electrical codes and choose appropriate protective devices rated for the intended circuit.
