Why Choose the ABB PLVS4052 Vertical Lateral Segregation Accessory?
The ABB PLVS4052 (1STQ008891A0000) is a dedicated vertical lateral segregation accessory from the ABB System pro E power range, designed for integration into compatible low-voltage electrical distribution switchboards. Identified by the manufacturer's designation SEGR.VERT.LAT. H=400MM D=500MM INT.UP., this component is specified for a 400 mm height, a 500 mm nominal switchboard depth and a lateral vertical segregation arrangement.
In professional switchboard construction, segregation components help establish physical boundaries between designated internal areas. The ABB PLVS4052 supports the planned separation of adjacent switchboard spaces, helping electrical panel builders coordinate compartment layouts, equipment positioning and the integration of compatible internal barriers within the modular System pro E power enclosure system.
The manufacturer's designation also includes the INT.UP. configuration reference, which distinguishes this accessory from variants intended for other segregation arrangements. With its 400 mm specified height and 500 mm depth configuration, the ABB 1STQ008891A0000 provides a manufacturer-specific solution for industrial, commercial and infrastructure electrical distribution projects requiring compatible lateral segregation components.

Vertical Lateral Segregation for 500 mm Deep System pro E Power Switchboards
The ABB PLVS4052 is intended for compatible System pro E power low-voltage electrical distribution assemblies requiring a designated vertical lateral segregation component. Internal segregation is an important consideration in professional switchboard design, particularly where electrical equipment, conductors and connection spaces must be arranged within defined physical boundaries.
The manufacturer's SEGR.VERT.LAT. designation identifies a component associated with vertical segregation at a lateral position within the switchboard arrangement. When correctly installed alongside compatible partitions and structural components, lateral segregation accessories can help establish physical boundaries between neighbouring internal spaces.
The 400 mm specified height is a key selection parameter. Panel builders should coordinate this dimension with the intended compartment layout, neighbouring segregation components and structural fixing points. The component should not be assumed to provide a continuous partition across the full enclosure height without additional compatible parts.
The 500 mm nominal switchboard depth identifies the intended depth configuration. This is particularly important when selecting lateral segregation accessories because enclosure depth influences the positioning of internal structures, mounting systems and compartment boundaries. The PLVS4052 should be matched to the corresponding System pro E power assembly dimensions.
The manufacturer's INT.UP. reference forms part of the official product designation. It should be retained when selecting the accessory and comparing it with ABB assembly drawings. Its precise installation meaning, including any intermediate or upper positioning requirements, should be confirmed using ABB technical documentation rather than inferred from the abbreviation alone.
Internal segregation may help establish separation between busbar areas, functional units and electrical connection compartments. However, the ABB PLVS4052 alone does not establish a particular form of internal separation, such as Form 2, Form 3 or Form 4. The achieved arrangement depends on the complete combination of compatible barriers, partitions, enclosure components and installed electrical equipment.
The PLVS4052 is a mechanical segregation accessory, not a busbar, circuit breaker or electrical protection device. It does not independently determine the switchboard's rated current, short-circuit withstand capability, insulation performance or degree of protection against access to hazardous parts. These characteristics must be established through the design and verification of the complete electrical assembly.
The ABB System pro E power range provides a modular platform for professional low-voltage switchboard construction. Compatible enclosure structures, busbar arrangements, mounting accessories and segregation components allow electrical panel builders to develop application-specific distribution assemblies. The PLVS4052 contributes to this system through its designated lateral segregation configuration for a 500 mm deep enclosure arrangement.
Before installation, panel builders should verify the selected enclosure depth, lateral mounting position, required segregation layout, fixing requirements and compatibility with adjacent components. The completed low-voltage switchboard should be designed and verified in accordance with applicable IEC 61439 requirements, including the intended internal separation arrangement and relevant electrical and mechanical clearances.
