7GDS288931R0000 ABB 288931 Separation 4B Type 8 – Switchgear Internal Separation Component

Why Choose the ABB 288931 Separation 4B Type 8?

The ABB 288931 Separation 4B Type 8 (7GDS288931R0000) is a dedicated internal separation component for industrial low-voltage switchgear and electrical distribution assemblies. Listed within the ABB GT product group, this component is identified for a Form 4b, Type 8 separation arrangement, supporting the physical segregation of designated areas within compatible switchgear assemblies.

Internal separation components are important elements of electrical switchgear construction, helping establish barriers between functional units, busbar compartments and cable termination areas according to the applicable assembly design. The ABB 288931 is specifically designated as a 4B Type 8 separation component, making it suitable for installations where this particular internal segregation arrangement and ABB component reference are specified.

Identified by manufacturer order code 7GDS288931R0000, the ABB 288931 provides a clearly identifiable component for switchgear construction, maintenance and refurbishment. Its separation function supports the intended compartment arrangement of compatible electrical assemblies, helping maintain physical segregation and orderly integration of internal switchgear components when correctly installed.

Reliable Internal Separation for Industrial Switchgear Assemblies

Internal separation is an important design consideration in low-voltage switchgear assemblies. Under the principles of IEC 61439-2, forms of internal separation describe how busbars, functional units and external conductor terminals are segregated within an assembly. Form 4b arrangements provide separation between busbars and functional units, between individual functional units, and between terminals for external conductors associated with different functional units, with the terminals separated from their associated functional units.

The ABB 288931 Separation 4B Type 8 is identified for a specific internal separation arrangement within the ABB GT product group. When incorporated into the correct assembly configuration, it can contribute to the intended physical segregation of switchgear compartments. The Type 8 designation should be interpreted according to the applicable ABB assembly documentation, while the overall Form 4b classification depends on the complete switchgear construction rather than an individual separation component.

Correct selection and installation of internal barriers help maintain the designed compartment arrangement during equipment assembly, maintenance and replacement. The completed switchgear assembly must be assessed as a whole for its electrical safety, accessibility, ingress protection and applicable standards compliance.

Typical Applications

• Industrial low-voltage switchgear assemblies.
• Electrical power distribution switchboards.
• Switchgear installations incorporating Form 4b internal separation arrangements.
• Compatible ABB Type 8 compartment separation configurations.
• Internal segregation of switchgear functional units and associated connection areas.
• Industrial electrical distribution cabinet construction.
• Replacement of specified ABB internal separation components.
• Switchgear refurbishment, maintenance and compartment restoration projects.
