Construction distribution board XS-S 32A 2x230V IP44 sockets Doktorvolt DV-5077-F

Complete equipment for the construction site

The DV-5077-F construction distribution board is a ready-to-use distribution device designed for temporary power supply on construction sites, in warehouses, and workshops. The plastic enclosure, in grey (front) and black (rear), houses full switchgear - no additional purchases or manual wiring are required.

The socket configuration includes two single-phase Type E sockets (230V, 16A, with protective earth pin) and one three-phase CEE socket (400V, 32A). This combination allows for the simultaneous connection of both small hand tools (drills, grinders) and larger machines requiring three-phase power - such as concrete mixers, compressors, or pumps.

Safety is ensured by two MCBs: B16 (single-pole) protecting the single-phase circuits and C32 (three-pole) protecting the CEE socket. The prospective short-circuit current is ≤6 kA - sufficient for typical construction conditions.

The wiring is made of Bitner brand H07V-K cables with a cross-section of 2,5/4 mm². Protective conductors have yellow-green insulation, neutral conductors are blue, and supply conductors are black. This color coding facilitates identification during any potential installation modifications.

Operating conditions and resistance

The IP44 protection rating means the enclosure is sealed against solid objects larger than 1 mm and protected against water splashes from any direction. For a distribution board operating in the open air, this is the minimum required for daily use on a construction site - protecting against dust raised during material cutting and accidental contact with water.

The enclosure is UV-resistant, which is important during multi-month exposure to sunlight. The plastic will not crack or deform under temperatures ranging from -25°C to +50°C - the distribution board will perform well during both autumn finishing works and winter structural assembly.

Compact dimensions of 224 × 133 × 110 mm allow the device to be mounted even in tight spaces - near fence posts, on scaffolding, or inside welfare containers. An inspection window allows quick access to the terminals without the need to dismantle the entire enclosure.

Certificates and application

The manufacturer declares compliance with the IEC 61439 standard, which specifies requirements for low-voltage switchgear and controlgear assemblies. The DOKTORVOLT quality management system is certified by TÜV SÜD according to ISO 9001:2015 - confirming the repeatability of production processes and the quality control of every unit.

The DV-5077-F distribution board belongs to the XS series - stationary distribution devices intended for temporary power supply. An RDF coefficient of 0.8 indicates the continuous load capacity for the cyclic operating character typical of a construction site.

The set includes mounting plugs and two rubber cable glands for introducing external cables - installation consists of hanging the enclosure in the chosen location and connecting the supply line.
