Why Choose the ABB 831802 ARIA 75 Slotted Cover Plate 22M?
The ABB 831802 ARIA 75 Slotted Cover Plate 22M is a purpose-designed modular front cover for compatible ABB ARIA 75 electrical enclosures. Featuring a cut-out for 22 modular units, this accessory provides a convenient front-facing opening for suitably arranged DIN-rail electrical devices. It is particularly useful for electrical distribution assemblies where circuit breakers, protective devices or other modular components need to remain accessible through an internal cover system.
Identified by ABB extended product type AR075R03 and order code 4TBA831802C0100, the cover plate is manufactured from grey plastic and has manufacturer-listed dimensions of 423 mm wide × 150 mm high × 7.25 mm deep. ABB specifies an IP20 degree of protection for this individual cover accessory. Its non-transparent design and defined modular opening make it a practical component for professionally assembled electrical distribution boards.
The ABB AR075R03 belongs to the ARIA enclosure accessory system and is designed to work within an appropriate modular cover arrangement. Its single-row, 22-module configuration enables panel builders to create a consistent equipment-access area while covering the surrounding internal cabinet space. The product is supplied as an individual cover plate rather than a complete enclosure, mounting frame or electrical distribution assembly.

Dimensional clarification: ABB's product datasheet lists the net product dimensions as 423 × 150 × 7.25 mm. The separate A to F measurements come from ABB's catalogue drawing of individual modular cover plates and describe that drawing's reference geometry. They should not be substituted for the product's net width, height and depth.
Understanding the ABB ARIA 75 22-Module Cover Plate
The ABB 831802 AR075R03 is intended for electrical distribution assemblies using modular DIN-rail equipment. Its 22-module cut-out provides a front opening through which appropriately positioned devices can be accessed. The cover also conceals adjacent internal areas, helping create a more organised equipment-facing layout. Actual device alignment depends on the mounting arrangement, DIN-rail positioning and the design of the completed electrical assembly.
ABB's general-purpose enclosure catalogue identifies the 831802 as the slotted version of an individual modular cover plate, with the 831803 representing the corresponding solid configuration. The slotted plate has a catalogue drawing opening dimension of 396 × 46 mm, while the solid alternative has no equivalent equipment opening. Selecting between these versions allows panel builders to configure the internal front according to whether a particular position needs modular device access.
The manufacturer specifies IP20 for the ABB 831802 accessory. This classification should not be confused with the environmental ingress protection of the complete outer enclosure. IP20 describes the specified protection of the individual cover, while the safety and protection of the finished distribution board depend on the enclosure, equipment layout, internal barriers, cable entries and correct assembly. The cover must be installed in accordance with ABB guidance and the applicable electrical installation requirements.
