4TBA831057C0100 ABB 831057 AR054D03 ARIA 54 Mounting Frame 3 Rows 54 Modules

Why Choose the ABB 831057 ARIA 54 Mounting Frame?

The ABB 831057, manufacturer designation AR054D03, is a dedicated 54-module mounting frame for ABB ARIA 54 electrical enclosures. Designed to support the installation of modular electrical equipment, this mounting frame provides a structured internal arrangement with 3 rows of 18 modules, making it suitable for low-voltage distribution and control assemblies.

Part of the established ABB ARIA enclosure accessories range, the 831057 is also described as the PAMR54 mounting frame. Its removable frame arrangement incorporates perforated, reinforced DIN rails, helping electrical panel builders organise modular protective and control devices within compatible ARIA 54 enclosures.

With manufacturer order code 4TBA831057C0100, nominal dimensions of 415 mm wide × 515 mm high × 35 mm deep and a net weight of approximately 1.23 kg, the ABB AR054D03 offers a practical internal mounting solution for professional electrical installations. Its dedicated design supports efficient panel assembly, equipment positioning and future maintenance.

Reliable Modular Equipment Mounting for ABB ARIA 54 Enclosures

A properly configured mounting frame is an important part of a low-voltage electrical distribution assembly. It provides the mechanical support needed to position modular electrical equipment in an organised arrangement, helping installers achieve consistent component alignment and maintain suitable access for wiring, inspection and servicing.

The ABB 831057 ARIA 54 mounting frame is designed specifically for the ARIA 54 enclosure format. Its three-row, 54-module arrangement provides 18 module positions on each row, allowing suitably sized modular devices to be distributed across the available mounting space.

The frame incorporates perforated, reinforced DIN rails as part of the ABB ARIA internal mounting system. DIN rail mounting is widely used for modular electrical equipment, including miniature circuit breakers, residual current devices, contactors, relays and associated control components, subject to their individual mounting requirements.

A key benefit of the ABB ARIA mounting system is its removable frame arrangement. This allows the mounting structure to be handled as a dedicated assembly component, supporting practical installation and maintenance workflows. The frame must be secured using the appropriate ABB fixing arrangement and installed according to the requirements of the compatible enclosure.

The nominal dimensions of 415 × 515 × 35 mm help identify the correct mounting frame for the intended ARIA 54 configuration. Its approximately 1.23 kg net weight also assists with equipment planning and handling during panel construction.

For a completed distribution assembly, the mounting frame can be combined with compatible ABB ARIA internal cover arrangements. The ARIA 54 range includes a solid front cover, a DIN-slotted front cover and modular plate options, allowing the enclosure's internal equipment arrangement to be configured according to the intended installation.

The ABB AR054D03 is a mechanical mounting accessory, not a complete electrical enclosure or protective device. It does not independently provide electrical insulation, ingress protection, overload protection or short-circuit protection. The completed assembly must use appropriate protective devices, covers, wiring and enclosure components in accordance with applicable electrical installation requirements.
