Why Choose the ABB ZLS741 Height Adaptor?
The ABB ZLS741 is a mounting rail height adaptor designed for use with the ABB SMISSLINE plug-in system. It provides 22.5 mm height compensation, allowing conventional DIN-rail-mounted devices to be installed alongside SMISSLINE components while maintaining a consistent installation depth within the distribution assembly.
Designed as a dedicated SMISSLINE system accessory, the ZLS741 provides a straightforward mechanical solution when standard DIN-rail devices need to be integrated into an installation containing SMISSLINE plug-in equipment. By compensating for the difference in mounting depth, it helps create an orderly and correctly aligned device arrangement.
The ZLS741 occupies one module and is supplied as a pack of 10 adaptors. Its compact format makes it suitable for distribution boards and modular assemblies where SMISSLINE equipment and conventional DIN-rail devices are installed together.

Integrating DIN-Rail Devices with SMISSLINE
ABB's SMISSLINE system provides a modular plug-in platform for electrical distribution and protection equipment. Where conventional DIN-rail-mounted devices need to be positioned alongside SMISSLINE components, differences in mounting depth can prevent the equipment fronts from aligning correctly. The ZLS741 addresses this mechanical installation requirement by providing 22.5 mm of height compensation.
Using the correct height adaptor helps installers achieve a consistent equipment layout without improvised mounting arrangements. The ZLS741 is therefore particularly useful when a distribution assembly combines SMISSLINE plug-in equipment with standard modular DIN-rail devices that are not mounted directly on the SMISSLINE socket system.
Typical Applications
- ABB SMISSLINE plug-in distribution systems.
- Mixed SMISSLINE and conventional DIN-rail installations.
- Electrical distribution boards and switchboards.
- Modular control and protection assemblies.
- Height compensation for standard DIN-rail devices.
- Installations requiring consistent front alignment between adjacent modular devices.
