Why Choose the ABB ED72SA Busbar Expansion?
The ABB ED72SA is a 2 panel-width (2PW) busbar combination set designed for ABB internal distribution systems. Mounted on EDF profile rails, it provides a coordinated horizontal busbar arrangement for professional sub-distribution assemblies and is designed for intermediate installation between compatible distribution panels.
The ED72SA has a 2 grid-unit (2GU) configuration measuring 300 mm high × 500 mm wide and provides 48 space units (PLE). It incorporates a 5-pole horizontal busbar system with five 12 × 5 mm copper busbars and a 40 mm busbar centre distance.
Designed for a maximum rated current of 250 A in ABB's current internal expansion system specification, the ED72SA uses ZX2BP2 busbar brackets and is suitable for compatible cabinets from 200 mm depth. EDF profile rails and field connectors are included for coordinated integration into the ABB distribution system.

Reliable Busbar Distribution for Electrical Installations
Busbar combination sets provide a structured means of distributing electrical power through compatible distribution assemblies while maintaining a coordinated internal layout. The ED72SA is designed to connect between distribution panels at the top and bottom, allowing it to serve as an intermediate busbar installation within the cabinet system.
With its 5-pole copper busbar system, 40 mm centre spacing and maximum rated current of 250 A, the ABB ED72SA provides a compact 2PW busbar expansion solution for professional electrical distribution and panel-building applications.
Typical Applications
- Electrical sub-distribution cabinets.
- Intermediate busbar sections between distribution panels.
- ABB internal expansion systems.
- Commercial building electrical distribution.
- Industrial distribution assemblies.
- Professional switchgear and panel-building installations.
