4TBA831040C0100 ABB 831040 AR043S03 Aria Slotted Inner Cover Plate for ARIA 43

Why Choose the ABB 831040 Aria Slotted Inner Cover Plate?

The ABB 831040 Slotted Inner Cover Plate is a purpose-designed punched internal cover plate with openings for DIN rail-mounted electrical equipment, manufactured for compatible ABB ARIA 43 electrical enclosures. Part of the ABB Aria Enclosures range, this accessory provides an organised front covering for modular electrical distribution assemblies while allowing access to the operating faces of appropriately positioned devices.

Also identified by the manufacturer's type reference AR043S03, the ABB 831040 is a grey plastic cover plate designed for a standard two-row distribution field accommodating up to 24 modular units, arranged as two rows of 12 modules. Its slotted construction distinguishes it from solid cover plates, making it suitable for assemblies containing compatible DIN rail-mounted circuit breakers, switches and other modular electrical equipment.

With nominal product dimensions of 379 × 261.8 × 79.4 mm (height × width × depth) and a net weight of approximately 0.597 kg, the ABB 831040 provides a purpose-made internal covering solution for the ARIA 43 enclosure format. Its accurately defined product reference and ABB order code 4TBA831040C0100 make it straightforward to identify for new installations, maintenance and replacement projects.

Slotted Internal Covering for Modular Electrical Distribution Equipment

The ABB 831040 AR043S03 is designed to provide a structured front covering within compatible ABB ARIA electrical enclosures. Its punched openings accommodate the operating faces of suitable DIN rail-mounted devices, allowing users and maintenance personnel to access relevant controls without unnecessarily exposing the surrounding internal wiring.

The cover plate is intended for a two-row, 24-module distribution arrangement. This makes it particularly useful for electrical assemblies containing modular circuit breakers, residual-current protective devices, switches and other compatible DIN rail-mounted equipment. The exact arrangement and device compatibility must be determined by the complete enclosure and mounting system.

Unlike the ABB 831039 solid inner cover plate, which provides an uninterrupted covering surface, the ABB 831040 slotted version incorporates openings specifically intended for modular electrical equipment. This distinction is important when selecting the correct cover plate for a distribution board requiring front access to installed protective or switching devices.

Manufactured from grey plastic, the ABB 831040 forms part of the ABB ARIA enclosure accessory system. It is an internal cover plate rather than a complete enclosure, and its use does not independently establish the ingress protection, impact resistance or electrical safety rating of the finished assembly. Correct device positioning, compatible mounting hardware and proper installation remain essential.

Typical Applications

• ABB ARIA 43 electrical enclosure assemblies.
• Low-voltage modular electrical distribution boards.
• Electrical panels containing DIN rail-mounted circuit breakers.
• Distribution assemblies with residual-current protective devices.
• Commercial electrical distribution installations.
• Industrial electrical control and distribution enclosures.
• Two-row modular distribution arrangements.
• Electrical enclosure assembly and panel building.
• Replacement of compatible ABB ARIA 43 punched cover plates.
• Electrical panel maintenance and refurbishment.
• Installations requiring a 24-module slotted internal cover plate.
• Professional electrical projects specifying the ABB AR043S03 cover plate.
