Why Choose the ABB AS233 Slotted Cover 750mm x 450mm for Distribution Boards?
The ABB STRIEBEL & JOHN AS233 (2CPX062850R9999) is a professional slotted distribution board cover designed for compatible ABB electrical distribution and interior expansion systems. Measuring 750 mm wide × 450 mm high × 26.5 mm deep, the AS233 provides a purpose-designed front covering for three-field-width, three-row distribution board arrangements.
Manufactured from plastic in RAL 7035 light grey, the ABB AS233 combines a durable, non-transparent cover construction with three horizontal slotted openings. These openings are intended for appropriately positioned modular electrical devices, allowing their operating fronts to remain accessible while the surrounding distribution board interior is covered.
The AS233 belongs to ABB's CombiLine interior expansion system accessory range and is included in the manufacturer's family of covers for rail-mounted devices with 150 mm row spacing. This makes correct model selection particularly important when matching the cover to an existing distribution board layout.
Its 90-degree press-and-turn fastening system provides a practical means of securing the removable cover to the compatible assembly. ABB specifies the product with an IP2XC protection classification, making it relevant to distribution board designs requiring the specified degree of protection against access to hazardous parts.
Identified by ABB order code 2CPX062850R9999, model AS233 and EAN 4011617628507, this genuine ABB accessory is suitable for professional panel-building, sub-distribution board construction and compatible replacement applications.

Slotted Design for Rail-Mounted Electrical Devices
The defining feature of the ABB AS233 is its slotted front cover construction.
The openings are designed to accommodate the operating fronts of appropriately positioned electrical devices within a compatible distribution board arrangement.
This can allow users to access relevant device operating handles while the surrounding internal components remain behind the cover.
The AS233 should be selected according to the actual device layout, mounting position and cover opening requirements.
It does not include circuit breakers, switches, fuses or other electrical devices. These must be selected and installed separately as part of the complete distribution assembly.
Three-Field Width and Three-Row Layout
The AS233 cover has a nominal three-field-width configuration, with an overall width of 750 mm.
Its height is 450 mm, corresponding to the specified three-row arrangement.
The cover belongs to ABB's range for rail-mounted devices with 150 mm row spacing.
Correct row spacing is important when selecting front covers because device openings must align with the electrical equipment behind the cover.
Installers should verify the field width, row spacing, cabinet arrangement and mounting positions before fitting the AS233.
IP2XC Protection Classification
ABB specifies the AS233 with an IP2XC protection classification.
The IP2X designation relates to protection against finger access to hazardous parts and the ingress of solid objects of the corresponding size.
The additional C designation relates to protection against access to hazardous parts using the specified tool-type access probe.
This classification is relevant to electrical distribution board designs where the front covering forms part of the intended protective arrangement.
However, IP2XC is not equivalent to IP54, IP55 or IP65. The AS233 should not be described as dust-tight or resistant to water jets.
The final protection rating of a complete distribution board depends on the assembled enclosure, its doors, internal covers, cable entries and installation conditions.
90-Degree Press-and-Turn Fastening
The ABB AS233 uses a 90-degree press-and-turn fastening system.
This provides a defined method for securing the cover to a compatible distribution board arrangement.
The cover is described as quick-locking and non-hinged, making it a removable cover rather than a permanently hinged access door.
For authorised maintenance, the fastening arrangement enables the cover to be removed using the appropriate procedure.
Electrical safety requirements must always be followed before removing the cover. The fasteners do not indicate whether internal components are electrically isolated.
RAL 7035 Light Grey Plastic Construction
The AS233 is manufactured from plastic and finished in RAL 7035 light grey.
The non-transparent construction provides a consistent front appearance for compatible electrical distribution assemblies.
RAL 7035 is widely used across electrical cabinets and distribution equipment, making the AS233 suitable for installations where matching enclosure components is important.
The product is a plastic cover, not a sheet-steel cover or complete metal enclosure.
Any cutting, drilling or other modifications must be evaluated against ABB's instructions and the protective requirements of the finished assembly.
ABB CombiLine Interior Expansion System Compatibility
The ABB AS233 is identified within the manufacturer's CombiLine interior expansion system accessory range.
ABB provides a selection of slotted and unslotted covers for different field widths and row arrangements.
The AS233 is the 450 × 750 mm slotted cover associated with the 150 mm row-spacing family.
The corresponding solid version is the ABB AG233, order code 2CPX062849R9999.
Where a closed cover without device openings is required, the AG233 may be the appropriate alternative, subject to confirmation of the complete installation requirements.
The AS233 must not be assumed interchangeable with other ABB slotted covers of similar dimensions without verifying the applicable row spacing and system compatibility.
Slotted AS233 Versus Solid AG233
ABB provides both slotted and unslotted covers for suitable distribution board configurations.
The AS233 includes front slots intended for compatible rail-mounted device arrangements.
The AG233 is the corresponding closed cover without these slots.
Both models are identified in ABB's 450 × 750 mm cover range, but they serve different front-cover requirements.
When selecting a replacement, the original cover model should be checked rather than relying only on the overall dimensions.
Professional Installation and Replacement
The ABB AS233 is intended for integration into a compatible electrical distribution board assembly.
It is not supplied as a complete distribution board and does not include an enclosure frame, busbars, circuit breakers or other internal electrical equipment.
Installation should follow the relevant ABB assembly instructions and the approved electrical design.
The position of the slotted openings must correspond to the installed devices, and any unused openings must be addressed using suitable manufacturer-approved components where required.
Electrical work must be undertaken by competent personnel following appropriate isolation and safety procedures.
