Construction distribution board cam switch 16A WDD 1x16A Mennekes Doktorvolt 6091 DV-6091-D

Industrial construction distribution board for harsh conditions

The WDD electrical distribution board is a compact solution designed for powering construction sites, workshops, and industrial areas. The enclosure measures 190×145×75 mm - its small format allows for convenient transport and placement even in tight spaces, e.g., near a site fence or inside a container.

Enclosure and protection against weather conditions

The hermetic enclosure provides an IP65 ingress protection rating, which means full protection against dust and water jets. The Mennekes Typ 1385 power socket operates in the IP44 class - it is resistant to solid foreign objects >1 mm and splashing water from any direction. This combination ensures the distribution board performs well both in rain and in the dusty environments typical of a construction site.

For secure cable entry, the manufacturer has installed a PG-21 cable gland (Ø13-18 mm), which further increases the sealing to IP68.

Electrical equipment and control

The heart of the distribution board is a three-phase L-0-P cam switch (500V, 16A) equipped with a lever and an S16 JD 9151 C6 nameplate. The L-0-P designation indicates three operating positions - L (line/phase), zero (off), and P (reversing motor rotation direction). This is essential when connecting devices that require a change in phase sequence, such as pumps or fans.

The continuous current rating RDF = 0.9 confirms the distribution board's ability to operate under near-continuous loads - not just during short-term current draws.

Application and compatibility

The red Mennekes power socket is a European standard - it is compatible with plugs used on most construction machinery, welders, or compressors available on the market. The distribution board supports a voltage of 230/400V AC at a frequency of 50 Hz, which corresponds to a typical industrial installation.

Typical places of use:

• Construction sites and roadworks - powering power tools,
• Car workshops and garages - connecting power equipment,
• Industrial plants - temporary power points,
• Outdoor events - power distribution for stages or catering stalls,
• Self-build home construction - a distribution board on the plot before the permanent installation is connected.

Production takes place in a management system certified by TÜV SÜD, which guarantees repeatable manufacturing quality and operational safety.
