Schneider Electric DBR416MF DBSeT 64-Way 100A Board

DBR416MF: DBSeT 64-way, 4-row, 100 A flush distribution board

The DBR416MF is a Schneider Electric DBSeT distribution board for low-voltage electrical distribution, supplied as an empty painted-steel enclosure with a DIN rail, an identification label and a plain flat door. It offers 64 modules of 18 mm in 4 rows (the datasheet gives the module count as 64 and the row count as 4, which works out to 16 modules in each row), is rated 100 A and is the flush-mounting version of its size. Seven Star LLC supplies the DBR416MF in Oman and the GCC as an independent supplier based in Muscat.

The reference breaks down as follows, based on the product title and datasheet and not on a published ordering key: DBR3, DBR4, DBR5 or DBR6 points to the number of rows, DBR416MF sits in the 4-row group, and the closing MF or MS letters correspond to flush mounting. Treat that reading as a navigation aid and confirm everything against the datasheet.

Fitting out and maintaining the DBR416MF

The enclosure is made of painted sheet steel, 1.2 mm thick, finished in White (RAL 9003). It carries an IP41 rating under IEC 60529 and IK08 under IEC 62262, and the stated ambient temperature for operation is 50 °C. IP41 suits dry indoor areas and not wash-down, outdoor or very dusty locations.

Because DBR416MF ships empty, the electrician installs the incomer, the outgoing devices and the cabling on site. Mount and level the enclosure, fit the devices on the DIN rail, label every circuit and torque connections according to the device data. Inspect terminals for heating marks during maintenance and test RCDs periodically.

Selection checklist and RFQ information for DBR416MF

• Count devices and positions: incomer, every outgoing breaker or RCBO, plus spare ways, compared with 64 modules in 4 rows.
• Confirm the wall: a recess for flush mounting, or a free wall face for the surface version of the same size.
• Check the incomer: isolator, MCB or RCCB, each up to 100 A according to the datasheet.
• Check that no single outgoing device exceeds the 63 A limit named for RCBOs and MCBs.
• List the devices you want supplied with the board, since the DBR416MF is an empty enclosure with a DIN rail and label.

For the RFQ please send the reference, quantity, delivery location, project name and whether you need the breakers quoted together with the board.

Where a 64-way board like the DBR416MF is used in Oman and the GCC

Boards of this kind distribute power inside buildings: site offices and accommodation blocks at oil and gas facilities, service buildings at power and desalination plants, workshops, warehouses and commercial premises. DBR416MF is aimed at the general-purpose, final-distribution end of that range, feeding lighting, sockets, small motors, air-conditioning units and control panels from a single incoming supply.

High summer temperatures in poorly ventilated electrical rooms reduce the margin against the 50 °C ambient limit, and dust and humidity matter for an IP41 board, so mention the room when you enquire.

What the 64-module capacity means for a layout

Capacity here is counted in 18 mm DIN modules, the width of a single-pole miniature breaker. DBR416MF provides 64 of them over 4 horizontal rows. A three-pole device takes three module positions, an RCBO or RCCB usually takes more than one, and the incomer also occupies space on the rail, so the number of circuits you can actually fit is lower than the headline count. Count every device and leave spares.

The next size down in the same mounting style is the DBR316MF with 48 modules over 3 rows, and the next size up is the DBR516MF with 80 modules over 5 rows. Every board in this group keeps the same 425 mm width and 124.9 mm depth and adds height as rows are added, which makes the 745 mm height of this unit the main number to check against wall space.

Flush mounting of the DBR416MF

As a flush board, this unit is built to sit in a recess so that only the front frame and door stand proud of the finished wall. The enclosure body measures 425 × 745 × 124.9 mm (W × H × D), so the wall recess has to take a body of that size with room for conduit or cable access. The recess is normally planned at first fix, reserving the 124.9 mm depth.

The packed weight is 8.6 kg and the carton measures 76.5 cm by 44.5 cm by 13.6 cm. Cables enter through a removable gland plate at the top and bottom of the enclosure, so the routing of feeders in the wall cavity can be planned top-down or bottom-up. The surface-mounted version of the same size is the DBR416MS, which swaps the recess for a wall-face installation; the datasheets list the same external width, height and depth, so the choice is about the building and not about capacity.

The DBR family compared with the DBR416MF

The DBR group covers the same 425 mm width and 124.9 mm depth at heights from 595 to 1045 mm. The table lists each reference with the figures taken from its datasheet, so you can see what changes with size and what does not.

Rated current, voltage range, door type and the 50 °C ambient limit stay constant down the table, while rows, modules, height and weight rise together.

Incomers and outgoers accepted by the DBR416MF

The datasheet lists the protection devices that can be fitted. For the incomer it allows an isolator, a miniature circuit breaker or an RCCB, each up to 100 A. For outgoing circuits it names RCBOs and miniature circuit breakers up to 63 A. The board is rated for 240…415 V AC at 50/60 Hz with an insulation voltage (Ui) of 500 V AC, and it is designed to IEC 61439-3 and IEC 61439-1, the standards for distribution boards operated by ordinary persons and the general rules for low-voltage assemblies.

It helps to keep two figures apart. The 100 A rating is the board’s rated current, which sets the ceiling for the incomer. The 63 A figure applies per outgoing device and does not mean every way can carry it at once; diversity and cable sizing decide the real loading.
