Schneider Electric DBV30606MS DBSeT VTPN 6+6 Board

DBV30606MS: VTPN DBSeT 6+6 way, 125 A surface three-phase board

The DBV30606MS is a Schneider Electric VTPN distribution board in the DBSeT range, built for three-phase low-voltage distribution at 125 A with a modular incomer. The datasheet lists 6 + 6 (outgoer) ways, a pan assembly, earthing bar and neutral bar, and a plain flat door on a painted steel enclosure. It is the surface-mounting version. Seven Star LLC supplies the DBV30606MS in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference from the title and datasheet, DBV3 relates to a three-phase board, the next digits (06, 12, 18, 24, 30 and 12) give the module counts of the two outgoer banks, and MF or MS gives surface mounting. In DBV30606MS the banks are 6 and 6, adding up to 12 outgoer ways. This is our reading of the names and not a published ordering key.

Short-circuit ratings and devices for the DBV30606MS

This family stands out for the short-circuit data given in the datasheet. The rated short-time withstand current (Icw) is 17 kA for 0.25 s and the rated peak withstand current (Ipk) is 34 kA. The impulse withstand voltage (Uimp) is 6 kV, the insulation voltage (Ui) is 500 V AC and the rated voltage is 240…415 V AC at 50/60 Hz on three phases. The board is designed to IEC 61439-3 and IEC 61439-1 and the datasheet lists DEKRA certification.

The options are RCBOs and miniature circuit breakers on the outgoing side and an isolator with an RCCB as the incomer. Those figures describe the assembly and should be compared with the prospective fault current at the point of installation and with the data of the devices fitted. The datasheet describes the incomer as modular, so the main protection is a modular device and not a moulded-case breaker; DBV30606MS is therefore not intended for incoming supplies above its 125 A rating.

Surface mounting of the DBV30606MS

This version fixes to the face of the wall, so there is no recess to form and the 124.9 mm depth stands in the room. The enclosure measures 425 × 555 × 124.9 mm (W × H × D), and the weight on the carton label is 13.335 kg, with a pack size of 55.5 cm by 42.5 cm by 12.49 cm. A board of this weight needs secure wall fixings, and the wall construction should be checked first.

Cables enter through the removable gland plate at the top and bottom of the enclosure, so surface conduit or trunking can be brought in from both directions. The flush-mount twin is the DBV30606MF, with a packed weight of 13.125 kg; the other listed figures are the same.

Commissioning and care of the DBV30606MS

The enclosure is painted sheet steel 1.2 mm thick in White (RAL 9003), with IP41 (IEC 60529) and IK08 ratings, and an ambient temperature of 50 °C for operation. IP41 limits use to indoor, dry places; for dust or splash exposure use another enclosure. The door is a plain flat door with no window.

After mounting, fit the incomer and outgoer devices on the pan assembly, connect neutral and earth conductors to their bars, label each way, and check the torque of every terminal. Test RCCBs and RCBOs on site and record the readings in the commissioning file. During service, thermal imaging under load is a useful check for loose connections. The datasheet lists an 18-month contractual warranty for DBV30606MS.

What the 6+6 outgoer layout provides

The datasheet lists the ways as 6 + 6 (outgoer). Two banks are given, which suggests the pan assembly is split into two ranks of outgoing positions, giving 12 single-pole spaces in total. As with every module-based board, a three-pole breaker or an RCBO takes more than one space, so the count of circuits will be lower than 12. Plan the layout by listing every device and add spare positions.

This is the smallest board in the group, so no smaller sibling exists, and the next size up is the DBV30612MS with 6 + 12 outgoer ways. All references keep the 425 mm width and 124.9 mm depth. Height of DBV30606MS is 555 mm and the packed weight is 13.335 kg, which is why lifting and wall space need checking before delivery.

Selection checklist and RFQ information for DBV30606MS

• Confirm a three-phase 240…415 V AC, 50/60 Hz supply and a maximum of 125 A.
• Compare the prospective fault level with the 17 kA / 0.25 s and 34 kA peak values.
• Count outgoers against 6 + 6 ways and allow for multi-pole devices and spares.
• Decide on flush or surface mounting and verify wall space for 425 × 555 × 124.9 mm.
• Decide whether the incomer and outgoer devices are to be supplied with the board.

For the RFQ please send the reference, quantity, delivery location, project name and a draft of the circuit schedule if one exists.

Technical specifications of the DBV30606MS

The VTPN DBV family compared with the DBV30606MS

The DBV references share the 125 A modular incomer, the 17 kA and 34 kA short-circuit values and the 425 mm width. The table shows the figures that change from one to the next.

The ways, height and weight grow with each step, while the rating, voltage and protection class stay constant. The datasheets give the recyclability as 96 %.

Where the DBV30606MS is typically used in Oman and the GCC

A three-phase board at 125 A with a modular incomer serves buildings that are larger than a villa but smaller than a plant substation: office floors, accommodation blocks, retail units, workshops, warehouses and utility buildings at oil and gas, power and desalination sites. It distributes three-phase and single-phase circuits to lighting, air-conditioning, pumps and small machines.

The 12 outgoer ways of DBV30606MS are suited to a floor or a building section where the circuits are known. In hot climates the 50 °C ambient limit and the IP41 rating should be checked against the actual room; an electrical room that is air-conditioned is generally well suited, a roof-top plant cabinet is not.
