Construction distribution board FRED 6x230V Mennekes Doktorvolt® 9627 sockets DV-9627-F

Compact power supply for construction sites and workshops

The FRED distribution board from the construction series is a ready-to-use distribution device equipped with six factory-installed single-phase 230 V / 16 A sockets. The sockets operate in the Type E standard (French system, 2p+E), ensuring compatibility with plugs commonly used in Poland and Europe.

The PVC housing has dimensions of 245 × 195 × 95 mm - it fits on a pallet and can be easily transported between workstations. The front plate is grey RAL 7035, and the rear plate is black. The set includes a PG-16 cable gland, which allows for the entry of a connection cable with a cross-section of up to 16 mm². The internal wiring consists of H07V-K wires with a cross-section of 2,5 mm² - yellow-green (protective), black, and blue (phase/neutral).

Resistance and operating conditions

The sockets have an IP44 ingress protection rating, which means protection against solid foreign objects >1 mm and splashing water from any direction - sufficient for use in the open air under a roof or in a damp workshop. The distribution board housing achieves an IP65 rating, so the dust tightness and protection against water jets are higher than for the sockets themselves.

The device operates at a rated voltage of 230 V / 50 Hz AC with a rated current of 16 A. The short-circuit capacity is ≤ 10 kA, and the RDF simultaneity factor is 0,8. This data allows for the correct selection of upstream protections - the distribution board itself does not contain circuit breakers or RCDs (hence the term "unenclosed"), but it is factory-wired and ready to be connected to a main panel or a generator.

Practical applications

Six independent sockets provide sufficient capacity for a construction crew working simultaneously with multiple tools - hammer drills, angle grinders, or work lighting. Typical installation sites:

• construction sites and roadwork areas,
• industrial halls during machine startup or maintenance,
• automotive workshops and garages,
• individual single-family house construction,
• green areas and outdoor events requiring temporary power.

During individual house construction, the distribution board serves as a power distribution point between working zones - e.g., the ground floor and first floor served by separate circuits.

Production quality and certificates

The manufacturer has implemented a quality management system certified by TÜV SÜD according to the ISO 9001:2015 standard. The design meets the requirements of the IEC 61439 standard, and the product itself bears the CE marking. For the installer, this means certainty that the distribution board has passed appropriate type tests and can be legally used within the European Union without additional formalities.

Production based on proven components - a hermetic surface-mounted box-type housing and factory-installed sockets - translates into the device's longevity, even with frequent plugging and unplugging and variable atmospheric conditions.
