Why Choose the ABB ZX21 DIN Rail?
The ABB ZX21 (2CPX039021R9999) is a professional 1-panel-width DIN rail designed for mounting electrical components within compatible ABB distribution systems. Part of the ABB DESUJ Sub Distribution product group, it provides a robust and standardised mounting platform for panel-building and internal expansion applications.
The ZX21 uses a standard 35 × 7.5 mm top-hat profile and has a length of 244 mm, corresponding to a 1 PW field width. Manufactured from 1 mm steel with a Sendzimir-galvanised surface, the rail combines mechanical strength with corrosion-resistant surface protection for professional electrical installations.
Designed specifically for mounting directly onto compatible mounting frames, the ZX21 provides a straightforward way to create a DIN rail mounting level within ABB cabinet assemblies. Its compact dimensions and system compatibility make it suitable for terminal blocks and other compatible DIN rail-mounted electrical equipment.
