Why Choose the ABB TL104S TwinLine Wall-Mounting Enclosure?
The ABB TL104S is a robust TwinLine wall-mounting electrical enclosure designed for sub-distribution and low-voltage electrical installations. As part of the ABB TwinLine enclosure system, it provides a durable, flexible housing for distribution equipment, metering components, CombiLine modules and mounting assemblies in indoor applications.
This enclosure combines a powder-coated sheet-steel construction with protection class II double insulation and an IP55 degree of protection. Its single-leaf door can be hinged on either the right or left and opens through approximately 180°, helping simplify installation, wiring and maintenance access.
With external dimensions of 650 mm high × 300 mm wide × 275 mm deep, the TL104S provides 48 space units within a compact one-panel-width format. It is pre-assembled for installation of metering and distribution fields, combination sets, CombiLine modules or mounting plates on EDF or WR mounting frames.

Flexible Enclosure for Sub-Distribution Systems
The ABB TwinLine system is designed to support modular low-voltage distribution arrangements in commercial, industrial and infrastructure installations. The TL104S provides a structured enclosure platform for organising protective devices, metering equipment and distribution components while maintaining reliable mechanical and environmental protection.
Its internal mounting arrangement supports EDF and WR mounting frames and can accommodate meter fields, distribution fields, combination sets, CombiLine modules or mounting plates. This modular construction helps electrical installers configure the enclosure efficiently for a wide range of sub-distribution requirements.
Typical Applications
- Electrical sub-distribution boards.
- Commercial building distribution systems.
- Industrial low-voltage control and distribution panels.
- Metering and protective-device assemblies.
- CombiLine modular distribution systems.
- Indoor wall-mounted electrical installations.
