Why Choose the ABB ZLS905E50-3LNLALB Starter Pack?
The ABB ZLS905E50-3LNLALB is a touch-proof 125 A starter pack for the SMISSLINE TP plug-in system, providing a 50-module distribution platform for compatible ABB protection and switching devices. Supplied under ABB order code 2CCA183193R0001, it incorporates the L1, L2 and L3 phase conductors, neutral conductor and LA/LB auxiliary busbars in one modular assembly.
As part of the ABB SMISSLINE TP plug-in system, the ZLS905E50-3LNLALB enables compatible protective devices to connect directly to the pluggable socket system. This architecture helps reduce conventional wiring, simplifies installation and maintenance, and provides IP2XB finger-safe protection when used together with the socket end piece.
With a 50-module capacity, 125 A rated current and 3LN LA LB configuration, this starter pack combines L1, L2, L3, N, LA and LB conductors. It measures 941 mm including the socket end piece, with an 897 mm busbar length, providing substantial capacity for modular three-phase, neutral and auxiliary distribution.

Reliable Power and Auxiliary Distribution
The ABB SMISSLINE TP system provides a modular approach to low-voltage electrical distribution by allowing compatible protective devices to connect directly to a pluggable socket and busbar system. This architecture supports efficient installation and maintenance while reducing the conventional wiring required between individual protective devices and the main distribution busbars.
The ZLS905E50-3LNLALB combines three-phase L1, L2 and L3 distribution, neutral and LA/LB auxiliary busbars within one 50-module starter pack. Its 125 A rating, touch-proof construction and integrated auxiliary conductors make it suitable for larger modular distribution assemblies requiring both main power and auxiliary connections.
Typical Applications
- Industrial electrical distribution panels.
- Commercial building distribution boards.
- Automation and machinery control cabinets.
- Infrastructure and facility power distribution systems.
- Modular protection and switching assemblies.
- SMISSLINE TP installations requiring three-phase, neutral and auxiliary busbar distribution.
