Why Choose the ABB ZLS928 Additional Socket?
The ABB ZLS928 is an 8-module additional socket designed for external neutral (N) and protective earth (PE) busbars within the ABB SMISSLINE TP plug-in system. Identified by ABB order code 2CCA183630R0001, it is specifically designed for the SMISSLINE 125 A system and provides a practical way to extend neutral and protective earth distribution alongside the main socket base.
The ZLS928 can be fitted to a compatible SMISSLINE socket base to accommodate an external N busbar, PE busbar, or both. Neutral terminals can then be clipped onto the additional socket to provide detachable neutral connections, making the accessory particularly useful where single-pole miniature circuit breakers are installed with an unswitched neutral.
An integrated 35 mm DIN-rail snap-on feature provides additional installation flexibility, allowing external N or PE busbars to be positioned within the distribution panel, including separately from the main SMISSLINE assembly. The 8-module ZLS928 forms part of ABB's modular plug-in distribution platform and, when used with the appropriate socket end piece, supports IP2XB finger-safe protection.

Flexible Neutral and Protective Earth Distribution
The ABB ZLS928 extends the SMISSLINE TP socket system by providing dedicated mounting for external neutral and protective earth busbars. This arrangement is particularly useful when single-pole protective devices are used with unswitched neutral conductors, as compatible neutral terminals can be clipped directly onto the additional socket to form detachable connections.
Its integrated 35 mm DIN-rail snap-on feature also allows external N and PE busbars to be positioned where required within the distribution panel rather than being restricted to the main socket assembly. This modular approach supports organised panel construction while retaining the installation flexibility associated with the SMISSLINE TP system.
Typical Applications
- ABB SMISSLINE TP plug-in distribution systems.
- External neutral busbar installations.
- External protective earth busbar installations.
- Distribution boards using single-pole miniature circuit breakers with unswitched neutrals.
- Commercial and industrial electrical distribution panels.
- Modular power distribution and control assemblies.
