Main Busbar Separation in Low-Voltage Switchgear Assemblies
The main busbar system forms an important part of a low-voltage electrical distribution assembly. It distributes power between incoming connections and the various outgoing circuits or functional units within the switchgear. Because these systems can carry substantial electrical currents, the surrounding mechanical layout and internal separation arrangements are important aspects of switchgear design.
The ABB 287205 MBB Separation Plate is intended to form part of the separation arrangement associated with the main busbar area. Internal separation components help define compartment boundaries, organise equipment spaces and support the segregation requirements specified by the switchgear manufacturer.
In low-voltage switchgear, internal separation arrangements may be designed to meet particular forms of separation under BS EN IEC 61439. However, the achieved form of separation depends on the complete assembly design, the positioning of all relevant barriers and the manufacturer's verified construction. The ABB 287205 plate does not independently establish a particular form of separation or safety classification.
Correct selection of the separation plate is important because different switchgear configurations can require different component dimensions, mounting arrangements and barrier geometries. ABB identifies several distinct MBB separation plate references, making the exact order code 7GDS287205R0000 essential when selecting this particular component.
During new switchgear construction or maintenance, the separation plate should be installed only in the configuration for which it is specified. The complete assembly must retain the required electrical clearances, creepage distances, mechanical protection and thermal performance following installation or replacement.
The ABB 287205 is a dedicated internal separation accessory, not a current-carrying busbar, circuit protection device or complete switchgear enclosure. Its suitability should be confirmed against the relevant ABB parts list, switchgear drawings and assembly instructions before installation.

Frequently Asked Questions
What is the ABB 287205 7GDS287205R0000 used for?
The ABB 287205 is an MBB separation plate used as part of the internal separation arrangement in compatible low-voltage switchgear assemblies. It helps establish physical separation around the main busbar area in accordance with the intended switchgear design.
What does MBB mean in the ABB 287205 product description?
MBB stands for main busbar. The ABB 287205 MBB Separation Plate is an accessory associated with the separation of the main busbar area within a compatible electrical distribution assembly.
What is the ABB order code for the 287205 MBB Separation Plate?
The ABB order code is 7GDS287205R0000. The manufacturer reference is 287205, and the product is listed under ABB's GT product group.
Which ABB switchgear systems are compatible with the 287205 separation plate?
The ABB 287205 is intended for switchgear configurations that specifically identify part 287205 or order code 7GDS287205R0000 in their assembly documentation. Compatibility with a particular switchgear model, panel size or busbar arrangement should be confirmed using the applicable ABB drawings and parts list.
Does the ABB 287205 provide electrical insulation?
The ABB 287205 is identified as a main busbar separation plate, but its material and specific dielectric properties should be confirmed from the applicable manufacturer documentation. It should not be assumed to provide a particular electrical insulation rating independently of the complete switchgear design.
Does the ABB 287205 determine the form of separation of a switchgear assembly?
No. The form of internal separation is determined by the complete switchgear assembly and its verified construction. The ABB 287205 may form part of that arrangement, but a particular separation classification cannot be established from this component alone.
Can the ABB 287205 be used as a replacement separation plate?
Yes, where the existing switchgear assembly specifies ABB part 287205. Before replacement, confirm the exact order code, mounting arrangement and compatibility with the installed busbar configuration. Work inside electrical switchgear must be carried out by appropriately qualified personnel using safe isolation procedures.
Is the ABB 287205 a complete busbar system?
No. The ABB 287205 7GDS287205R0000 is a separation plate accessory. It does not include the complete main busbar system, busbar supports, electrical connections or other switchgear components unless separately specified.
What should be checked before ordering the ABB 287205?
Confirm the ABB order code 7GDS287205R0000, the switchgear assembly reference, the applicable manufacturer's parts list and the intended mounting position. These checks are important because other ABB MBB separation plates have different part numbers and may not be interchangeable.
