Schneider Electric DBSP106MS DBSeT 2+6 Way Board

DBSP106MS: DBSeT 2+6 way single-phase surface enclosure

The DBSP106MS is a single-phase DBSeT distribution enclosure from Schneider Electric with 8 module positions, listed as 2+6 ways, a 100 A rating and a plain door. It arrives with a neutral link, earthing bar, neutral bar, comb busbar and identification label already supplied with the enclosure, which sets it apart from larger empty boards. It is the surface-mounting version of its size. Seven Star LLC supplies the DBSP106MS in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference from the title and datasheet, DBSP1 is the single-phase compact group, DBSP106MS carries 6 outgoing ways in addition to the two incomer ways, and the final MF or MS letters correspond to surface mounting. This is our interpretation of the naming and not a published ordering key, so check the datasheet.

Technical specifications of the DBSP106MS

Electrical ratings and busbar equipment of the DBSP106MS

The datasheet gives a rated current of 100 A, a rated operational voltage of 240 V AC, a rated impulse withstand voltage (Uimp) of 6 kV and a rated insulation voltage (Ui) of 500 V. It is a single-phase enclosure and is designed to IEC 61439-3 and IEC 61439-1; the datasheet also lists a DEKRA product certification. The impulse figure describes the ability to withstand transient overvoltage, the insulation figure describes dielectric strength, and neither is an operating voltage. A 240 V single-phase supply is the working condition.

The enclosure comes with a comb busbar for the module row, a neutral bar and a neutral link, and an earthing bar. That equipment saves bench work, since the neutral and earth distribution is part of the package, but the miniature breakers, RCBOs or other devices still have to be selected and bought separately. The datasheet does not list a device catalogue for this enclosure, so compatibility must be confirmed from the data of the devices you intend to fit.

Typical uses of a compact board such as the DBSP106MS in Oman and the GCC

A single-phase 2+6 board is generally used for small sub-distribution: a site cabin, a guard house, a pump house, a telecom shelter, a small workshop, a villa extension or a tenant fit-out. In the Gulf these boards usually carry air-conditioning, lighting, sockets and small control loads, and they sit in places where summer heat is the main stress.

The 8-module size of DBSP106MS suits installations with a modest circuit count. Where the building is air-conditioned the 50 °C ambient rating is rarely a concern, but a board inside an unventilated cabin in direct sun can exceed it. Mention the location when you ask for a quotation so that we can check ratings against the real conditions.

Selection checklist and RFQ information for DBSP106MS

• Confirm single-phase 240 V AC supply and a maximum of 100 A.
• Count the single-pole spaces your devices need against the 2+6 ways available.
• Choose flush or surface mounting according to the wall, and note the colour and IP rating listed for this exact reference (grey, IP40).
• Plan the cable entries against the 5 knock-outs at top and bottom and 2 on each side.
• Decide whether breakers are to be quoted with the enclosure.

For the RFQ please send the reference, quantity, project location, the list of outgoing devices if needed, and the delivery date you are working to.

Surface-mounted version: DBSP106MS

As a surface enclosure, DBSP106MS is fixed on the wall face and needs no recess. The outside dimensions are listed as 339 mm width, 104 mm height and 265 mm depth, as published. The labelling of height and depth appears to be rotated relative to the product photo, which shows a wide, landscape-style door, so check the dimension drawing when you plan the wall space. The datasheet gives the entry as 5 knock-outs at the top and bottom, plus 2 on each side.

Knock-outs allow cables to arrive from several directions, which suits trunking and conduit runs on an exposed wall. The flush-mount twin of this size is the DBSP106MF; note that it is not only a mounting variation, because the datasheet lists it with white paint and IP41 while this one is listed with grey and IP40.

Installation notes for the DBSP106MS

The body is powder-coated sheet steel, 1.2 mm thick, finished in Grey (RAL 7035), with an IP40 rating (closed door, IEC 60529) and IK08 (IEC 62262). The rated ambient temperature is 50 °C. Mount the enclosure, open only the knock-outs that you need, fit glands or bushes so that edges do not cut cable sheaths, and place the devices on the DIN rail. Connect neutral and earth conductors to their bars and use the label to document each circuit.

Before energising, verify polarity, insulation resistance and RCD operation using the test procedures applicable to the installation. DBSP106MS carries an 18-month contractual warranty in the datasheet. For maintenance, check the busbar teeth and terminals for discolouration, confirm that the door closes squarely and refresh the circuit labels after any modification.

The DBSP family compared with the DBSP106MS

The single-phase DBSP group runs from 8 to 20 module positions in flush and surface versions. The values below are copied from each datasheet; note that paint colour and IP rating are not the same on every reference, so read the last column.

Rated current (100 A), the 240 V AC operational voltage and the 6 kV impulse rating are constant. Width and weight rise with the way count, while the other two outside dimensions are the same, as published. The datasheets describe 96 % recyclability.

How the 2+6 ways are organised on the DBSP106MS

The datasheet lists the ways as 2+6. We read this as two positions reserved at the incoming end plus 6 positions for outgoing circuits, which sums to 8 module positions, matching the “8 module” in the title. Because breakers differ in width, treat the figure as a count of single-pole spaces and not as a count of circuits. A double-pole RCBO takes two spaces, so a typical layout holds fewer separate circuits than the headline suggests.

This is the smallest of the group, so there is no smaller sibling, and the next size up is the DBSP108MS with 2+8 ways. The 3.5 kg packed weight and 339 mm outside width of this unit grow with the way count while the other two dimensions stay the same across the family.
