Construction distribution board on a stand with cable and meter 3F TD-S/FI SKHU 32A 2x230V Doktorvolt 0502 DV-0502-F

Complete solution for construction site power supply

A portable three-phase distribution board mounted on an aluminum stand is a ready-to-use distribution device equipped with all necessary protection and measurement elements. The design based on a technopolymer enclosure (front plate in gray RAL 7035) ensures adequate rigidity while maintaining low mass - the entire unit weighs approximately 6 kg, allowing for easy relocation of the distribution board within the work area.

Power distribution and available output circuits

The device provides three output circuits, each covered by a separate overcurrent protection:

• Two single-phase sockets - French standard (Type E) with a grounding pin, 230 V / 16 A, manufacturer Mennekes, IP44 protection class.
• One power socket - three-phase CEE 400 V / 32 A, red color (Type CEE Type 3451), Mennekes, IP44.

All sockets are protected against indirect contact by an SEZ Type A RCD with parameters 40 A / 30 mA.

Overcurrent protection and energy measurement

Circuit	Protection	Characteristic
Single-phase sockets	single-pole circuit breaker C16	C curve - slower reaction to short-term current spikes
Power socket	three-pole circuit breaker C32	C curve - short-circuit strength ≤10 kA

The 3F / 7M / 12 mm² busbar distributes power between the individual internal circuits.

The built-in LE-02d MID F&F meter registers the energy consumption drawn by all loads connected to the distribution board - three-phase system 3 × 230/400 V AC, nominal current 5 A, maximum continuous up to (80)A. The MID certificate confirms metrological legalization enabling billing between parties.

Wiring, enclosure, and operating conditions

The distribution board is supplied as a device ready for immediate connection:

• H07RN-F connection cable - rubber cable with working cores 5 × 4 mm², length approximately 90 cm.
• Mennekes CEE ProTOP plug - five-pole (5P) for voltage 400 V / 32 A, IP44 protection degree.
• Internal H07V-K wiring with cross-sections from 2.5 to 6 mm².

The surface-mounted enclosure accommodates 12 modules of modular devices in one row; the rated insulation voltage is 1000 V. The EPDM rubber gasket maintains IP44 tightness - protecting against solid particles above 1 mm in diameter and water splashes; stainless steel mounting screws; the box dimensions are 360 ×250 ×185 mm, and after mounting on the stand, the total height reaches approximately 495 mm. The PG-21 gland allows for the introduction of an additional external cable.

Compliance with standards

The manufacturer has implemented a quality management system certified by TÜV SÜD according to ISO:9001:2015 and IEC61439 regarding low-voltage switchgear assemblies. The Low Voltage Directive (CE marking), CEI-23-48/49 enclosure design standard, and IEC670 for auxiliary equipment confirm the structural safety. The residual current device additionally meets the IEC61009‑1 standard for protective functions with pulsating AC type A residual current. The internal wiring has a CPR certificate confirming its fire reaction; the entire device is also compliant with the RoHS directive regarding hazardous substances in electrical and electronic equipment.
