4TBA831133C0100 ABB 831133 ARIA 108 IP54 Glazed Door Polyester Enclosure 835 x 1035 x 300mm 3-Point Lock

Why Choose the ABB 831133 ARIA 108 Glazed Door Electrical Enclosure?

The ABB 831133 ARIA 108 Glazed Door Electrical Enclosure is a large-format electrical cabinet designed to accommodate distribution, control, automation and switching equipment. Measuring 835 mm wide × 1035 mm high × 300 mm deep, this enclosure combines generous equipment accommodation with a transparent viewing door and a secure three-point locking arrangement. It is particularly useful for installations where electrical equipment must be protected while allowing operators to observe internal indicators, instruments or displays.

Manufactured from hot-pressed, glass-fibre reinforced polyester, the ABB 831133 features a durable, non-metallic cabinet body finished in RAL 7035 light grey. Its glazed-door configuration is rated IP54 for ingress protection and IK07 for mechanical impact resistance. These product-specific ratings make the enclosure suitable for appropriately designed commercial and industrial electrical installations where resistance to dust, splashing water and mechanical impacts is required.

Identified by ABB extended product type AR108T33 and order code 4TBA831133C0100, this cabinet belongs to the ABB ARIA universal polyester enclosure range. The single glazed door incorporates a 3 mm double-bit locking mechanism with three-point closure. Internal threaded mounting provisions accommodate compatible ABB ARIA mounting plates and frames, allowing panel builders to configure the enclosure for their chosen electrical equipment and installation requirements.

Key Advantages

IP54 Protection, Glazed Door Visibility and Three-Point Locking

The ABB 831133 AR108T33 is designed for electrical installations that benefit from visual monitoring of equipment behind a closed enclosure door. The transparent viewing section allows operators to observe suitably positioned meters, indicators, displays and control equipment without routinely opening the cabinet. This is particularly useful in electrical distribution and automation systems where equipment status may need to be checked during normal operation. The glazed door is a viewing feature rather than a substitute for appropriate isolation or safe maintenance procedures.

The enclosure has a product-specific IP54 ingress protection rating, indicating protection against dust ingress sufficient to prevent harmful deposits and against splashing water from any direction. Its IK07 impact resistance describes the mechanical impact performance of the specified enclosure construction. These ratings should not be confused with the higher protection levels available on some solid-door ABB ARIA enclosures. Any cable entries, glands, seals or enclosure modifications must be selected and installed appropriately to preserve the required protection of the completed electrical assembly.

The glass-fibre reinforced polyester housing provides a corrosion-resistant, non-metallic structure with protective insulating characteristics. ABB specifies a 1,000 V rated insulation voltage and material temperature resistance of up to 70 °C continuously, with peaks up to 130 °C. These values relate to the enclosure material and do not establish the permissible operating temperature of every installed electrical component. The three-point locking system and internal mounting provisions support secure cabinet closure and flexible equipment arrangement, provided the complete installation is correctly designed and assembled.
