Construction distribution board 32A 16A 3x230V protected by residual current device IP54 Doktorvolt JUN-S/FI DV-0294-F

Comprehensive power supply for the construction site

The JUN-S/FI distribution board is a complete solution for electrical energy distribution in working conditions. It is equipped with three single-phase 230V sockets based on the 1P+N+PE standard, each with a rated current of 16A - sufficient to simultaneously power power tools, work lighting, or chargers. Also available are two CEE power sockets: one 16A and one 32A (both in a three-phase 3P+N+PE configuration), allowing for the connection of heavier machinery - welding machines, concrete mixers, or compressors.

The enclosure dimensions are 223 × 310 × 112 mm, which, with its surface-mounted design, allows for convenient installation directly on a wall or pole.

Protections for every circuit

Each circuit has its own overcurrent protection - the installer does not need to expand the internal distribution board or add external fuse blocks. The single-phase sockets are protected by a C16A circuit breaker (single-pole, 6 kA), and each power socket by a dedicated circuit breaker (C16A for the 16A socket and C32A for the 32A socket, both three-pole). The whole is completed by an AC type 40A/4P/30mA residual current device (RCD), which minimizes the risk of electric shock in case of insulation damage.

The prospective short-circuit current is ≤6 kA, and the RDF coefficient is 0.7 - which means an allowable continuous load at 70% of the rated current during a standard duty cycle.

Weather-resistant enclosure

The IP54 protection rating means full sealing against dust and protection against water splashes from any direction - the distribution board will perform well during rain, in intense dust, or on an open construction site. The plastic enclosure is resistant to UV radiation, so it will not crack or deform under the influence of the sun. The front plate is gray, the rear is black - this distinction facilitates orientation during installation.

The operating temperature range from -25°C to +50°C allows for year-round use, even in frost or heat. A PG21 membrane is included, allowing for the introduction of an additional cable.

Quality and standards confirmed by certificates

Production takes place in the modern facility of Doktorvolt in Malichów (Opole Voivodeship). The distribution board complies with the IEC 61439 standard, confirmed by TÜV SÜD certificates and the ISO 9001:2015 quality management system. The internal wiring is made with Bitner brand wires - H07V-K control cables with cross-sections of 2.5 and 4 mm² (yellow-green core = protective, blue = neutral, black = phase), ensuring durable and safe internal connections.
