Modular Distribution Box ELEKTROPLAST RH-18 1x18 Surface-Mounted IP65 (36.18)

ELEKTROPLAST RH-18 1x18 surface-mounted distribution box (model 36.18) is a compact, weather-resistant enclosure designed to accommodate a single DIN-rail row with up to 18 modular devices. The housing is intended for surface installation in environments that require dust- and water-protected electrical distribution points. It accepts standard DIN-rail mounted circuit breakers, terminal blocks and similar modular equipment commonly used in residential, commercial and light industrial electrical installations.

Advantages

The enclosure provides an IP65 degree of protection, offering resistance to dust ingress and splash or jet water exposure suitable for indoor or sheltered outdoor locations. Its surface-mounted design simplifies installation on walls or panels without the need for recessed mounting. The box supports a standard row of modular components, enabling organised wiring and easy access for maintenance or expansion. Robust construction materials improve mechanical durability while maintaining compact external dimensions for efficient space use.

Suitable for

• Installation of DIN-rail circuit breakers and miniature protective devices
• Distribution points in apartments, small businesses and utility rooms
• Connection and termination with terminal blocks and busbars
• Surface-mounted electrical panels where IP65 protection is required

Key specifications

• Capacity: single row for up to 18 modular devices
• Mounting type: surface-mounted enclosure
• Protection rating: IP65 (dust-tight and protected against water jets/splashes)
• Intended equipment: DIN-rail mounted breakers, terminal blocks and modular devices
• Suitable environments: indoor and sheltered outdoor locations requiring sealed enclosures

How to use

Place the modular devices on the internal DIN rail and secure them according to the devices' mounting instructions. Route incoming and outgoing conductors through the designated cable entries or gland points while maintaining proper clearances and mechanical protection. Fix the enclosure to a flat surface using appropriate anchors or screws for the substrate, then close and seal the cover to preserve the IP65 protection. Observe applicable electrical codes and verify that protective device ratings and conductor sizes match the circuit requirements before energising.

Usage recommendations

For reliable performance, install the box in a location protected from direct high-pressure water jets and avoid prolonged immersion. Use appropriately rated cable glands or conduit fittings for external cable entries to maintain the IP65 seal. Ensure ventilation and heat dissipation considerations are met when populating the enclosure with multiple high-current devices, and follow local wiring regulations and safety standards during installation and servicing.
