Why Choose the ABB AS33 Slotted Cover 750 × 450 mm 3PW?
The ABB AS33 Slotted Cover is a purpose-designed front cover for compatible ABB electrical distribution board assemblies. Measuring 750 mm wide × 450 mm high, this three-panel-wide (3PW) cover features device access slots for electrical distribution installations requiring a slotted front covering arrangement.
Identified by ABB order code 2CPX062826R9999, the AS33 belongs to the DESUJ Sub Distribution product group. Its 750 mm width and 450 mm height provide a defined cover format for compatible ABB sub-distribution systems, making it suitable for professional electrical panel construction and replacement projects.
The slotted design allows the cover to be used where the distribution board's front layout requires access openings for compatible electrical devices. Unlike a solid cover, the AS33 is intended for an arrangement in which the cover openings correspond to the installed equipment and the manufacturer's specified internal mounting configuration.
For electrical contractors, switchboard manufacturers and maintenance engineers, the ABB AS33 provides a clearly identified accessory for compatible distribution assemblies. Selecting the correct model helps maintain consistent cover dimensions, alignment and integration with the surrounding enclosure components.

Slotted Cover Design for Electrical Device Access
The ABB AS33 is identified as a slotted cover, meaning it incorporates openings intended for the corresponding electrical equipment arrangement. In a compatible distribution board, these openings provide access to designated device operating areas while the remaining cover surface forms part of the front covering system.
The cover's 750 mm width makes it suitable for the specified three-panel-wide arrangement, while its 450 mm height determines the vertical area covered. Both dimensions must be matched to the enclosure's internal mounting structure and the intended device layout.
Before fitting a slotted cover, installers should confirm that the device positions align with the cover openings. Unused openings and any supplementary blanking components must be addressed according to the manufacturer's instructions to maintain the intended protection of the completed assembly.
750 mm Three-Panel-Width Distribution Board Configuration
The 3PW designation identifies the AS33 as a three-panel-wide cover. Its specified width of 750 mm is an important selection criterion for compatible ABB distribution board layouts.
At 450 mm high, the AS33 covers a defined vertical section of the enclosure. Depending on the distribution board configuration, it may be installed alongside other compatible cover sections to create the required front covering arrangement.
Nominal cover dimensions should always be considered alongside the fixing points, internal equipment positions and enclosure design. Covers with similar measurements are not necessarily interchangeable, particularly where the number or arrangement of device openings differs.
Professional Installation and Compatibility Checks
For a new distribution board, the correct cover should be selected from the manufacturer's specified component arrangement. The ABB AS33 should be used where the enclosure design calls for this model and its corresponding 750 × 450 mm slotted format.
For refurbishment or replacement, the existing cover reference should be compared with AS33 and order code 2CPX062826R9999. Matching the exact model helps reduce the risk of incorrect fixing geometry or misaligned device openings.
Installation should be carried out by appropriately qualified personnel. The completed distribution board must provide the required protection against access to hazardous parts and comply with the applicable electrical installation requirements.
