Construction distribution board XS-S/FI 16A 2x230V RCD IP54 with Siemens protection and Doktorvolt DV-5527-D sockets

Ready-made solution for construction sites and workshops

The DV-5527-D distribution board is a complete distribution set designed for temporary power supply on construction sites, in workshops, or production halls. In one enclosure, you will find everything needed to safely connect electrical devices - without the need to select and purchase individual components separately.

The device is equipped with two single-phase Schuko sockets (1P + N + PE, 16 A, 230 V), to which you can connect typical power tools, work lighting, or portable machinery. Sockets of this standard are widely used in Europe - they fit most plugs used in Poland and abroad.

Siemens protection - full installation protection

Safety is ensured by branded components from a German manufacturer:

• B16 MCB, 1P, 6 kA - protects the circuit against overload and short circuits. The B characteristic means a fast response to short circuits (3-5× rated current), which is important for installations with small-cross-section wires.
• 25A / 300mA RCD, type AC - detects leakage current to earth (e.g., through a user's body or damaged insulation) and instantly disconnects the power. The 300 mA differential current is the standard for general circuits - it effectively protects against electric shock while remaining resistant to accidental trips caused by so-called leakage currents.

All internal wires (black phase, blue neutral, yellow-green protective) have a cross-section of H07V-K 2,5 mm², ensuring sufficient current-carrying capacity for the 16 A circuit even at full load of both sockets simultaneously.

Resistance to weather conditions

The plastic enclosure provides an IP54 protection rating - protecting against dust ingress and water splashes from any direction. It is not completely dust-tight or waterproof (not suitable for submersion), but it easily withstands rain, workshop dust, or splashing during floor cleaning.

Additional resistance to UV radiation ensures that the enclosure does not become brittle or fade under sunlight - the distribution board can operate outdoors all season without material degradation.

The operating temperature range from -25°C to +50°C allows for use both in winter (unless the temperature drops below -25°C) and in summer under full sun.

Dimensions, mounting, and standards

The compact enclosure has dimensions of 224 × 133 × 110 mm (without sockets) - it fits even in small spaces: near structural columns, in a workshop corner, or on the wall of a welfare unit. The grey front / black back color scheme allows it to match most facades or technical interiors.

The set includes mounting plugs and two rubber cable glands through which you will introduce the power cables - without the need for additional sealing elements.

Production takes place under the control of the TÜV SÜD ISO 9001:2015 quality management system. The distribution board meets the requirements of the IEC 61439 standard (low-voltage switchgear and controlgear assemblies) and carries the CE marking. Each unit undergoes routine tests confirming the compliance of electrical and mechanical parameters with the manufacturer's declaration.
