1STQ009123A0000 ABB PRVS8041 Rear Vertical Segregation Panel H800 W400 Internal Upper System pro E Power

Why Choose the ABB PRVS8041 System pro E Power Rear Vertical Segregation Panel?

The ABB PRVS8041 (1STQ009123A0000) is a dedicated rear vertical segregation accessory for ABB System pro E Power low-voltage electrical distribution switchboards. Specified for a nominal segregation arrangement measuring 800 mm in height and 400 mm in width, this component supports the creation of defined internal separation boundaries within compatible modular switchboard assemblies.

The manufacturer's designation, SEGR.VERT.REAR H=800MM W=400MM INT.UP., identifies a rear vertical segregation component incorporating an internal upper arrangement. This configuration is intended for electrical switchboard designs requiring a particular rear compartment separation layout, allowing panel builders to select a manufacturer-specific accessory for the appropriate installation position.

As part of the ABB System pro E Power range, the PRVS8041 is intended for integration with compatible enclosure structures, internal supports and associated segregation components. Its vertical orientation makes it relevant to switchboard arrangements requiring a physical barrier between designated internal areas at the rear of the assembly.

The ABB PRVS8041 rear vertical segregation panel provides electrical engineers, switchboard manufacturers and installation contractors with a clearly identified accessory for the specified 800 mm × 400 mm nominal configuration. Its manufacturer order code, 1STQ009123A0000, supports accurate purchasing, technical specification and compatible replacement identification.

Rear Vertical Segregation for Modular Electrical Distribution Switchboards

The ABB PRVS8041 rear vertical segregation accessory is intended to support physical compartment separation within compatible System pro E Power low-voltage electrical switchboards. Internal segregation is an important consideration in distribution board construction, particularly where the design requires defined boundaries between busbar systems, functional units, cable connection areas and other internal equipment.

The PRVS8041 is specified for a rear vertical segregation arrangement. This identifies the intended orientation and location of the component within the compatible switchboard structure. Unlike horizontal segregation accessories, which create boundaries across designated horizontal areas, rear vertical segregation components contribute to separation along the corresponding vertical compartment arrangement.

The manufacturer's designation identifies a nominal segregation height of 800 mm and a nominal configuration width of 400 mm. These dimensions are essential for selecting the correct accessory, but they should not automatically be interpreted as the exact physical dimensions of the manufactured component. Precise panel measurements, fixing positions and installation clearances should be checked against ABB technical documentation.

The additional INT.UP. designation indicates an internal upper arrangement. This distinguishes the PRVS8041 from other PRVS-series segregation accessories intended for different configurations. Correct selection depends on the complete switchboard layout, including the location of structural members, mounting supports and adjacent compartment barriers.

Using the appropriate manufacturer-specific segregation component helps panel builders maintain a coordinated internal assembly. The PRVS8041 should be installed with the compatible ABB enclosure structures and complementary accessories required by the selected System pro E Power configuration.

Supporting Internal Separation and IEC/EN 61439 Switchboard Design

Low-voltage switchboards may require different degrees of internal separation depending on their electrical design, operational requirements and maintenance arrangements. The IEC/EN 61439 series provides the framework for the verification of low-voltage switchgear and controlgear assemblies, while internal separation arrangements are commonly described using recognised segregation forms.

A rear vertical segregation component such as the ABB PRVS8041 can contribute to the physical barriers used within a complete switchboard design. However, the manufacturer's designation does not independently specify a particular segregation form, and the installation of one accessory alone does not establish the finished assembly's classification.

For example, Form 2 arrangements separate busbars from functional units, while Form 3 arrangements additionally provide separation between individual functional units. The distinction between subdivisions such as Form 2a, Form 2b, Form 3a and Form 3b depends on how terminals are separated relative to the busbars and other functional units.

The PRVS8041 should therefore be considered as one part of the complete internal segregation scheme. The final design must account for the location of busbars, circuit-breakers, outgoing connections, terminals, enclosure structures and all required separation barriers.

The PRVS8041 is a mechanical switchboard accessory, not a protective switching device or complete electrical distribution board. It does not independently determine rated current, short-circuit withstand performance, ingress protection or IEC/EN 61439 conformity. These characteristics depend on the verified design and construction of the completed switchboard assembly.

Selecting and Installing the ABB PRVS8041

When specifying the ABB PRVS8041, confirm that the intended electrical switchboard belongs to the System pro E Power range and requires the corresponding rear vertical segregation arrangement. The specified 800 mm nominal height, 400 mm nominal width and internal upper configuration should match the assembly design.

The manufacturer order code 1STQ009123A0000 should be used for purchasing and recording the component in the project's bill of materials. This helps distinguish the PRVS8041 from other PRVS-series accessories with different nominal heights, widths or segregation arrangements.

Before installation, the panel builder should verify the intended mounting position, relevant structural supports and any required fixing or complementary segregation components. Particular attention should be given to the internal upper arrangement identified in the product designation.

Installation should be undertaken by appropriately qualified personnel following the applicable ABB System pro E Power assembly instructions. The finished switchboard must be assessed as a complete assembly to confirm that its internal separation, mechanical construction and electrical characteristics satisfy the project's requirements.
