Why Choose the ABB ED91SA Busbar Expansion?
The ABB ED91SA is a professional 1PW busbar expansion combination set for ABB low-voltage sub-distribution systems. Supplied under ABB order code 2CPX037816R9999, it is designed as an internal expansion system mounted on EDF profiles for busbars and terminal equipment.
As part of the ABB DESUJ Sub Distribution range, the ED91SA has a 3GU / 450 mm installation height, 1PW / 250 mm field width and 36 space units. It incorporates a horizontal 5-pole copper busbar system and is suitable for use in cabinets from 200 mm depth.
The busbar assembly uses five copper bars measuring 12 × 5 mm with a 40 mm busbar centre distance and ABB ZX2BP2 busbar brackets. The system is rated up to 250 A and is additionally equipped with a DIN rail mounted on an ED33P2 deep angle piece, providing a coordinated solution for busbar and terminal expansion.

Structured Busbar Expansion for Sub-Distribution Systems
The ABB ED91SA provides a coordinated way to extend the internal busbar arrangement of a low-voltage distribution cabinet. Its 5-pole copper busbar system provides a structured power-distribution path while the additional DIN rail supports terminal equipment within the same 1PW assembly.
The combination set is designed to be plugged into the distribution panel at either the top or bottom and secured to the cabinet on the opposite side. With a minimum required cabinet depth of 200 mm, included EDF profile rails and a compact 450 × 250 mm format, it provides an integrated solution for professional distribution-board construction.
Typical Applications
- ABB low-voltage sub-distribution cabinets.
- Busbar expansion within modular distribution systems.
- Power distribution and terminal sections.
- Commercial electrical distribution boards.
- Industrial switchgear and control assemblies.
- Professional panel building and cabinet expansion.
