Why Choose the ABB RZ166 Horizontal Partition?
The ABB RZ166 is a robust horizontal sheet-steel partition designed for internal separation within ABB low-voltage distribution cabinets. As part of the ABB DESUJ Sub Distribution and CombiLine N interior expansion system, it provides a purpose-designed partitioning solution for compatible TriLine® cabinets and WR mounting frames.
Designed for a 3-field-width configuration, the RZ166 is suitable for installations with a field width of 750 mm and a cabinet depth of 625 mm. Its sheet-steel construction provides a durable physical division within the cabinet, helping panel builders organise separate equipment areas and create structured internal layouts.
The RZ166 includes an additional mounting profile for assembly on the WR mounting frame and is supplied as a dedicated component for ABB cabinet systems. The partition is not fault-arc-proof and is intended for applications where mechanical separation and organised equipment installation are required rather than arc-resistant compartmentalisation.

Reliable Internal Separation for Distribution Cabinets
Horizontal partitions such as the ABB RZ166 allow electrical panel builders to divide the internal space of distribution cabinets into clearly defined equipment areas. Sheet-steel separation supports organised cabinet construction and provides a robust physical barrier between compatible sections of the electrical assembly.
The RZ166 is specifically designed for installation with ABB WR mounting frames in compatible TriLine® cabinets. Its three-field-width format and 625 mm cabinet-depth configuration make it suitable for larger modular distribution arrangements where dependable horizontal separation is required.
Typical Applications
- Low-voltage sub-distribution cabinets.
- ABB TriLine® cabinet systems.
- CombiLine N interior expansion assemblies.
- WR mounting frame installations.
- Industrial and commercial electrical distribution panels.
- Cabinet layouts requiring horizontal separation across three field widths.
