Why Choose the ABB ED55A Busbar Expansion?
The ABB ED55A is a 1 PW busbar expansion combination set for ABB low-voltage distribution systems, designed to extend a distribution panel with a dedicated horizontal busbar section. Supplied as a coordinated internal expansion assembly, it is mounted on EDF profiles for integration into compatible ABB distribution cabinets.
The ED55A has a 1 PW field width of 250 mm and a 2 GU height of 300 mm, providing 24 space units. Its three-pole horizontal busbar system uses three 12 × 5 mm copper busbars with a 60 mm busbar centre distance, providing a robust distribution arrangement with a maximum rated current of 360 A.
Designed for cabinets from 200 mm depth, the ED55A combination set is plugged into the distribution panel at the top or bottom and secured to the cabinet on the opposite side. Plastic covers with a 90° push-turn closure and RAL 7035 finish complete the assembly, while EDF profile rails and field connectors are included.

Structured Busbar Expansion for Low-Voltage Distribution
The ABB ED55A provides a compact 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, provide a structured three-pole distribution path 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 a 1 PW width, 2 GU height and 24 space units, the ED55A provides an integrated ABB solution for extending 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.
- Panel-building and switchgear assemblies.
- Distribution fields requiring integrated copper busbar expansion.
