Construction distribution board with meter 3F Siemens pTD-S/FI 16A 2x230V Mennekes Schuko sockets Doktorvolt 4784 DV-4784-D

Power solution for temporary sites

The construction distribution board with a three-phase meter is designed for temporary power supply on construction sites, during roadworks, and in industrial plants and workshops requiring the connection of power equipment. The device is equipped with all necessary installation components: a residual current circuit breaker 40A / 30mA / 3P+N, overcurrent protection for the sockets, and a three-phase energy consumption meter SENTRON PAC1600 with MID approval, allowing for legal verification of electricity measurement by network providers.

The enclosure with an IP65 protection rating made of technopolymer ensures tightness against dust and precipitation. The front plate is grey RAL 7035, and the door is made of polycarbonate—a material resistant to impact and UV radiation. An EPDM rubber seal and stainless steel screws maintain the construction's tightness over a long period of use in open areas. The enclosure dimensions of 360 × 260 × 125 mm allow for surface mounting even in limited spaces.

Sockets and modular apparatus

Three sockets are mounted on the front of the distribution board:

• Two single-phase sockets (German Schuko system) with a voltage of 230V / 16A, each in IP54 protection class. Protected by an individual C16 overcurrent breaker (1-pole, 10kA).
• CEE power socket single-phase/three-phase 400V / 16A / 5-pin, red (type 1385), IP44 class. Protected by a C32 breaker (3-pole, 10kA).

The distribution board includes a three-phase busbar 7-module / 16mm², wiring made of H07V-K conductors (cross-section from 2.5 to 6 mm², colors yellow-green / black / blue), and a set of mounting screws with caps. A PG-16 cable gland is included in the set.

Safety and standard

The device meets the requirements of EU directives confirmed by certificates:

Certificate / standard	Scope
CE	Compliance with the Low Voltage Directive
IEC 61439	Low-voltage switchgear and controlgear assemblies tests
CEI-23-48/49	Socket standards
IEC 670	Enclosures for electrical apparatus
TÜV SÜD ISO 9001:2015	Quality management system

The overcurrent breakers also possess CEBEC, IMQ, and VDE certificates. The short-circuit strength of the distribution board is ≤10 kA, and the Diversity Factor is 0.7.

The manufacturer has implemented a certified TÜV SÜD management system ensuring high production quality and transparent customer service. The distribution board is ready for connection—simply bring the supply cables and mount the device on a wall or temporary structure.
