4TBA831050N0100 ABB 831050 ARIA 54 Blind Door with 3-Point Lock 415 x 515 x 40mm

Why Choose the ABB 831050 ARIA 54 Blind Door and Lock?

The ABB 831050 ARIA 54 Blind Door and Lock is a purpose-designed replacement enclosure door featuring a 3-point locking mechanism for compatible ABB ARIA 54 electrical cabinets. Supplied as a solid, non-glazed door with a locking arrangement, this accessory provides a practical solution for replacing damaged enclosure doors or maintaining the security and protection of electrical distribution and control equipment.

Part of the ABB ARIA Enclosures range, the 831050 is designed for the ARIA 54 enclosure format and features a 3 mm double-bit locking system. The three-point closure arrangement helps secure the door at multiple positions, supporting consistent closure against the enclosure body. Its solid grey construction conceals the electrical equipment housed inside the cabinet, making it suitable for installations where a transparent viewing panel is not required.

Identified by ABB order code 4TBA831050N0100 and manufacturer reference AR831050, this replacement door measures 415 mm wide × 515 mm high × 40 mm deep. Manufactured from a grey plastic-based enclosure material, it is intended to integrate with the compatible ABB ARIA 54 cabinet system. It is a door and lock accessory only, not a complete electrical enclosure, and should be selected using the exact manufacturer reference to ensure the correct fit.

Secure Three-Point Door Closure for ABB ARIA 54 Electrical Enclosures

The ABB 831050 ARIA 54 blind door is designed to restore or maintain the protective front closure of a compatible electrical enclosure. Electrical distribution and control cabinets rely on correctly fitted doors to restrict access to internal equipment and support the protective characteristics of the completed assembly. The solid, non-glazed construction provides a closed front surface without a viewing window, making it suitable where direct visual inspection of equipment through the door is not required.

The 3-point locking arrangement is an important feature of this replacement component. Unlike a single-point closure, a three-point system secures the door at multiple positions, helping maintain consistent closure along the cabinet opening. The 3 mm double-bit lock is designed for the corresponding ABB ARIA 54 arrangement. The lock should be operated using the correct compatible key or tool, and any replacement locking components should be selected according to ABB's accessory guidance.

Although ABB ARIA enclosure assemblies are available with high levels of environmental protection, the 831050 replacement door does not independently establish an ingress protection rating for a completed installation. The achieved protection depends on the compatible cabinet, sealing components, hinges, door alignment, cable entries and correct assembly. Before returning equipment to service, installers should inspect the enclosure sealing surfaces, verify the operation of all three locking points and ensure that the replacement door closes correctly. Electrical enclosure maintenance should be carried out by competent personnel following appropriate isolation and safety procedures.
