4TBA831101C0100 ABB 831101 ARIA 86 Solid Inner Cover Plate Grey 561.8 x 790 x 79.4mm

Why Choose the ABB 831101 ARIA 86 Solid Inner Cover Plate?

The ABB 831101 ARIA 86 Solid Inner Cover Plate is a purpose-designed electrical enclosure accessory for compatible ABB ARIA 86 universal polyester enclosures. Designed to provide a continuous internal front covering, this solid plate helps separate the accessible front area of an enclosure from equipment installed behind it. It is an ideal choice for professional electrical panel builders, contractors and maintenance engineers who require a plain inner cover without preformed openings for modular electrical devices.

Identified by manufacturer type AR086C03 and ABB order code 4TBA831101C0100, this cover plate is part of ABB's coordinated ARIA enclosure accessory system. Manufactured from grey plastic, the plate features a solid, non-transparent design and is intended to fit the ARIA 86 enclosure format. Its manufacturer-listed dimensions are 561.8 mm wide × 790 mm high × 79.4 mm deep.

Unlike an equipment mounting plate, the ABB 831101 serves as an internal front cover rather than the main structural surface for mounting electrical components. Its closed design is useful for enclosure arrangements where a plain protective front is preferred, while the corresponding ARIA 86 cover plate with modular equipment openings is available as a separate accessory. This makes the 831101 a practical option for new cabinet assemblies, refurbishment work and replacement of existing solid inner covers.

Understanding Solid Inner Cover Plates for ABB ARIA Electrical Enclosures

The ABB 831101 AR086C03 is a full internal cover plate intended for the ARIA 86 enclosure format. In a typical electrical enclosure assembly, the internal front cover provides a covering between the front access area and components positioned further inside the cabinet. The 831101 features a solid, closed design, making it appropriate where an uninterrupted front panel is required rather than a cover with openings for modular circuit breakers or other DIN-rail equipment.

ABB's ARIA system provides several alternative internal front arrangements for different electrical assembly requirements. The AR086C03 is the solid full-cover option, while the AR086S03, order code 4TBA831102C0100, provides a front cover with openings for modular equipment. ABB also lists the AR086D03 mounting frame, order code 4TBA831103C0100, for the ARIA 86 internal system. Selecting the correct combination of cover, frame and mounting accessories helps achieve an appropriate equipment layout.

The ABB 831101 is an enclosure accessory rather than a complete protective enclosure. Its plastic construction and closed front should not be interpreted as an independent IP rating, electrical insulation classification or guarantee of protection against contact with live parts. Those characteristics depend on the completed assembly, including the outer cabinet, equipment arrangement, fixings, access provisions and installation method. Any modifications to the cover should be checked against ABB's instructions and the applicable electrical assembly requirements.

Typical Applications

• Solid internal front covering within ABB ARIA 86 electrical enclosures.
• Electrical distribution cabinets requiring a plain inner cover.
• Industrial control panels with equipment mounted behind a closed front plate.
• Commercial electrical enclosure assemblies.
• Building services electrical control equipment.
• Custom electrical panel layouts using ABB ARIA accessories.
• Electrical cabinet refurbishment and maintenance projects.
• Replacement of existing ABB AR086C03 solid cover plates.
• Enclosure configurations without front openings for modular electrical devices.
• Professional electrical panel-building applications.
• Equipment housing where a non-transparent internal front is preferred.
• Coordinated ABB ARIA 86 enclosure accessory installations.
