Construction distribution board Siemens pTD-S/FI protection devices 32A 16A 4x230V Mennekes Schuko sockets Doktorvolt 4869 DV-4869-D

Complete distribution set for construction sites and workshops

The pTD-S/Fi construction distribution board is a ready-to-use distribution device from the Doktorvolt PREMIUM series. A complete Siemens protection system and proven Mennekes connection equipment—including both industrial power sockets and four German standard Schuko sockets (type F)—are enclosed in a single surface-mounted housing. The product is delivered as a fully wired set—simply connect the power supply and you can start working.

The housing, with dimensions 360 × 260 × 125 mm, accommodates 12 modules on a single TH/TS 35 rail. It is made of technopolymer—a material resistant to impact and weather conditions. The front plate is gray RAL 7035, while the rear plate is black. The door is made of polycarbonate, the seal from EPDM rubber, and the mounting screws from stainless steel. The enclosure protection rating is IP44, which means an effective barrier against objects >1 mm and water splashes. A PG-16 cable gland is included to facilitate cable entry.

Sockets and equipment - complete connection system

The following are mounted on the front panel of the distribution board:

Type	Parameters	Quantity	IP
Mennekes power socket	400 V / 32 A / 5P	1 pc.	IP44
Mennekes power socket	400 V / 16 A / 5P	1 pc.	IP44
Mennekes Schuko socket	230 V / 16 A / type F	4 pcs.	IP54

The power sockets are red (Mennekes Types 3451 and 1385 respectively)—their higher IP44 protection rating allows for outdoor use even in the rain. The four blue Schuko sockets have an even higher protection rating of IP54, meaning they are dust-tight and protected against water jets from any angle.

Siemens electrical protections - overcurrent and residual current protection

Safety is ensured by branded Siemens components:

• Residual Current Circuit Breaker (RCCB) - 40 A / 30 mA / 4P, type A - protects the entire installation below the distribution board against electric shock from indirect contact.
• MCB for power sockets:
  • C32 /3P / 6 kA - for the main socket,
  • C16 /3P / 10 kA - for the smaller socket.
• MCB for Schuko sockets:
  • Two C16 /1P / 10 kA breakers - each protects a pair of sockets.

The three-phase busbar has a cross-section of 16 mm² and accommodates full phase-neutral and protective wiring. The wires are H07V-K flexible cables:

• yellow-green (protective) - cross-section 2.5-4 mm²
• black (phase) - cross-section 2.5-6 mm²
• blue (neutral) - cross-section 2.5-6 mm²

The manufacturer recommends using wires with a cross-section no smaller than specified above for continuous load.

Compliance with standards and operating conditions

The distribution board complies with the IEC 61439-3 standard, confirming its suitability as a distribution device for construction use. Enclosure certification includes CE and CEI-23-48/49; Siemens equipment additionally holds CEBEC, IMQ, and VDE certificates for MCBs, and VDE, EAC, and ÖVE for the RCCB.

The device operates at a rated voltage of 230/400 V AC, a rated current of up to 40 A, and a short-circuit strength of Icc ≤ 10 kA. The diversity factor (RDF) is 0.7, allowing for a realistic estimation of load capacity during simultaneous operation of multiple receivers.

Production is carried out in a management system certified by TÜV SÜD (ISO 9001:2015).
