Why Choose the ABB ED56A Busbar Expansion?
The ABB ED56A is a 2 PW busbar expansion combination set designed for structured internal expansion of compatible ABB low-voltage distribution cabinets. Mounted on EDF profiles, it provides a coordinated three-pole horizontal busbar section for extending power distribution within a cabinet assembly.
The ED56A has a 2 PW field width of 500 mm and a 2 GU height of 300 mm, providing 48 space units. Its three-pole system uses three 12 × 5 mm copper busbars arranged horizontally with a 60 mm busbar centre distance and supported by ABB ZB5 busbar holders.
Rated for a maximum current of 360 A, the ED56A is suitable for compatible cabinets from 200 mm depth. The combination set is plugged into the distribution panel at the top or bottom and secured to the cabinet on the opposite side, with EDF profile rails and field connectors included for coordinated installation.

Structured Busbar Expansion for Low-Voltage Distribution
The ABB ED56A provides a practical method of extending a compatible distribution panel with a dedicated horizontal busbar section. Its three 12 × 5 mm copper busbars, arranged with a 60 mm centre distance, create a structured three-pole distribution system with a maximum rated current of 360 A.
The combination set is designed to plug into the distribution panel at either the top or bottom and is secured to the cabinet on the opposite side. With its 2 PW width, 2 GU height and 48 space units, the ED56A provides a coordinated ABB solution for expanding busbar distribution within compatible low-voltage cabinet assemblies.
Typical Applications
- ABB low-voltage sub-distribution cabinets.
- Horizontal three-pole busbar expansion.
- Commercial building power distribution assemblies.
- Industrial low-voltage distribution systems.
- Electrical panel-building and switchgear assemblies.
- Distribution fields requiring integrated copper busbar expansion.
