Why Choose the ABB AG21 Solid Cover 500 × 150 mm 2PW?
The ABB AG21 Solid Cover is a purpose-designed front cover for compatible ABB electrical distribution board assemblies. Measuring 500 mm wide × 150 mm high, this two-panel-wide (2PW) solid cover provides a closed front covering for distribution board sections where device access slots are not required.
Identified by ABB order code 2CPX062811R9999, the AG21 belongs to the DESUJ Sub Distribution product group. Its solid, unslotted design makes it suitable for compatible enclosure sections requiring a continuous front cover rather than openings for operating electrical devices.
For electrical contractors, panel builders and maintenance engineers, choosing the correct cover helps ensure that the finished distribution board matches the intended ABB enclosure configuration. The AG21 offers a manufacturer-designated component with a clearly specified 500 × 150 mm format.
The ABB AG21 is suitable for new distribution board construction, compatible enclosure refurbishment and replacement of an existing matching cover. Before installation, the internal mounting arrangement, fixing points and associated enclosure components should be checked against ABB's assembly instructions.

Solid Cover Design for Electrical Distribution Boards
The ABB AG21 is identified as a solid cover, meaning its front surface does not incorporate the device access slots associated with slotted distribution board covers. This makes it appropriate for compatible sections where a continuous covering panel is specified.
Solid covers can be used within electrical distribution assemblies to cover areas not intended for direct operation of front-access electrical devices. The cover must still be matched to the correct ABB enclosure, internal structure and fixing arrangement.
Using a model-specific cover helps avoid the fitting problems that may occur with improvised or incorrectly sized panels. The AG21 should be selected where the ABB assembly documentation specifies this model or its exact equivalent.
500 mm Two-Panel-Width Cover Configuration
The 2PW designation identifies the ABB AG21 as a two-panel-wide cover. Its specified 500 mm width is a key dimension when planning a compatible distribution board interior.
The cover's 150 mm height makes it a relatively short front covering section within the corresponding ABB system. It may be used as part of a larger arrangement containing multiple cover sections, depending on the enclosure design.
Cover width and height are not the only compatibility considerations. Installers should also check the fixing locations, mounting supports, adjacent covers and internal equipment clearance before completing the assembly.
Selecting and Installing the Correct ABB AG21 Cover
For a new installation, confirm that the distribution board specification calls for the ABB AG21 and that the intended cover location measures 500 × 150 mm.
For replacement work, compare the existing component's model and order code with AG21 / 2CPX062811R9999. Similar-looking ABB covers may have different dimensions, device openings or mounting arrangements.
Electrical distribution board covers should be fitted by appropriately qualified personnel. The completed assembly must maintain the required protection against access to hazardous parts and comply with the applicable installation requirements.
