Construction distribution board XS 16A 2x230V CEE IP44 without socket protection Doktorvolt DV-5114-D

Construction site power supply - three sockets in one enclosure

The DV-5114-D distribution board offers three connection points in a compact stationary enclosure. Two single-phase Schuko sockets (1P+N+PE) allow for the connection of typical power tools and household appliances operating at a voltage of 230 V and a current of up to 16 A. The third socket is a three-phase CEE (3P+N+PE) at 400 V / 16 A - useful for concrete mixers, welding machines, or compressors requiring three phases. This configuration ensures that a single distribution board can handle both small finishing works and heavier equipment during the structural stage.

The enclosure accommodates power cables with a cross-section of H07V-K 2,5 mm²: the protective conductor in yellow-green insulation, the neutral in blue, and the phase in black. A 2.5 mm² cross-section with a rated load of up to 32 A provides an adequate safety margin.

Resistance to weather conditions

The IP44 protection rating means a barrier against solid bodies larger than 1 mm and splashing water from any direction. On an open construction site, this is the minimum required to prevent rain or dust from damaging the components. The plastic enclosure is additionally resistant to UV radiation - it will not crack or deform under sunlight throughout the entire working season.

The operating temperature range from -25 °C to +50 °C allows the distribution board to be used both in winter (during masonry or plastering) and in summer. The front panel of the enclosure is gray, and the rear is black - a neutral and practical color scheme.

Installation without surprises

The enclosure dimensions are 224 × 133 × 110 mm - the distribution board will fit on a steel pole, a formwork wall, or a temporary wooden structure. The set includes mounting plugs and two rubber glands through which the wires are routed - the gaps around the cables are protected against moisture.

The inspection window allows quick access to the connection box without dismantling the entire enclosure. The wires are already pre-routed to the sockets - the installer only connects the power from the grid side, and the distribution board is ready for work.

Certification and standards

Production takes place under the TÜV SÜD ISO 9001:2015 quality management system, and each unit undergoes individual tests confirming compliance with the IEC 61439 standard. The CE marking testifies to compliance with EU directive requirements regarding electromagnetic compatibility and operational safety. The manufacturer - the company Doktorvolt from Malichów in the Opole region - has specialized in construction distribution boards since 2013.
