Schneider Electric DBR216MF DBSeT 32-way 100 A board

DBR216MF: DBSeT 32-way flush mount distribution board

The DBR216MF is a Schneider Electric DBSeT low-voltage distribution board in painted white sheet steel, rated 100 A and arranged with two DIN rails with 16 modules of 18 mm each, giving 32 modules. The datasheet lists the type as a distribution board for low-voltage electrical distribution, supplied as an enclosure with DIN rail and an identification label, for flush installation. Seven Star LLC supplies the DBR216MF in Oman and the GCC as an independent supplier based in Muscat.

How to read DBR216MF: DBR is the board series, 2 stands for the number of rows, 16 for the modules per row, and the final letters MF or MS follow the mounting style. The datasheet title for this reference reads “32 ways, 100A, 2 row, flush mount”, and we have followed the title wording rather than a published ordering table.

Protective devices that fit the DBR216MF

The board is rated 100 A and accepts, according to the datasheet, an isolator, a miniature circuit-breaker or an RCCB of up to 100 A as incomer. As outgoers it accepts miniature circuit-breakers or RCBOs of up to 63 A. With 32 modules available on the DIN rails, a typical arrangement is an incomer plus a larger set of final circuits arranged in two tiers, with room for spare ways.

A module count is not a circuit count: a two-pole or four-pole device uses several modules, and the incoming device also occupies space. Add up the device widths before settling on the this unit. Keep the total load inside the 100 A rating and apply diversity as the design standard allows.

Wiring and cable entry on DBR216MF

The datasheet lists a removable gland plate at top and bottom. That arrangement lets the installer drill or punch the plate away from the board and avoid metal swarf inside the live area. Use glands or conduit fittings that suit the cable and maintain the IP41 rating, and bond the metal enclosure and door to the protective earth according to the wiring rules.

Apply the identification label so each way can be traced, and keep a circuit schedule with the board. Unused ways should be covered with blanking pieces from the device range so that live parts are not accessible when the door is open.

Where the DBR216MF is used in Oman and the GCC

Boards of this size appear in villas, apartments, offices, shops, small workshops and site cabins. In Oman and the GCC the main stress is heat: the datasheet gives an operating temperature of 50 °C, so a board in a hot plant room, a roof enclosure or a shaded corridor should be checked against that figure. Dust and humidity are other factors, and IP41 is for indoor use; outdoor or washdown locations call for a different enclosure type.

Technical specifications of the DBR216MF

Selection checklist for DBR216MF

• Count the modules of the incomer, outgoers and RCDs and compare with 32.
• Check that the incomer is not above 100 A and the outgoers not above 63 A.
• Confirm the flush mounting suits the wall construction.
• Measure the opening or wall face against 425 x 445 x 124.9 mm.
• Check the ambient temperature against the 50 °C listed.
• Plan the entries on the top and bottom gland plates.
• Confirm the standards required for the project, as the datasheet lists IEC 61439-1 and 61439-3.

Flush mounting and what it means for DBR216MF

The flush version is built into a wall recess so that only the door and frame stand proud of the finished surface. It is the usual choice in new-build interior walls where a neat look matters, and it requires the recess to be prepared before the board is fixed.

The datasheet gives the same outer dimensions of 425 x 445 x 124.9 mm for the this unit, so measure the wall opening or the wall face against those numbers and allow working room for the door to open. The plain flat door is fitted to a frame that carries the identification label, and the board earns its IP41 rating only when the door is closed and unused cable entries are covered.

Sizing the DBR216MF: one row or two rows

The this unit has 32 modules. The two-row board doubles the modules without widening the board, which is useful when a wall is wide enough but not tall. All four references share a width of 425 mm and the same 100 A rating, so the choice is about capacity and mounting style.
