Why Choose the ABB MBN262 N+PE / Terminal Expansion 2PW?
The ABB MBN262 is an unassembled N/PE busbar and terminal expansion module designed for ABB CombiLine distribution assemblies. Supplied under ABB order code 2CPX041760R9999, it combines provision for horizontal neutral and protective-earth busbars with additional DIN rail mounting space for terminal blocks.
The MBN262 supports a 2-pole horizontal busbar system using ZX149 busbar holders and accommodates up to two copper busbars. The busbar arrangement has a 92 mm rail spacing and supports a maximum rated current of 630 A with a short-time withstand current of 20 kA. The required copper busbars are ordered separately.
With a height of 300 mm, width of 500 mm and depth of 260 mm, the MBN262 corresponds to a 2 RE × 2 PW configuration and provides 48 space units. Its usable width is 438 mm, while the installation depth can be continuously adjusted from 90–145 mm to support flexible terminal and busbar integration.
Key Advantages

Integrated N/PE Distribution and Terminal Mounting
N/PE expansion modules such as the ABB MBN262 combine busbar distribution and terminal mounting within a single modular panel section. The horizontal two-pole busbar arrangement provides dedicated infrastructure for neutral and protective-earth distribution, while the additional DIN rail supports structured installation of terminal blocks for outgoing and internal conductors.
The ABB CombiLine system uses modular interior components to create configurable distribution assemblies. With a maximum rated current of 630 A, 48 space units, 438 mm usable width and continuously adjustable mounting depth, the MBN262 provides a flexible solution for integrating N/PE distribution and terminal connections into compatible cabinets.
Typical Applications
- ABB CombiLine modular distribution assemblies.
- Neutral and protective-earth busbar distribution.
- Terminal-block mounting and conductor termination.
- Commercial and industrial sub-distribution boards.
- Electrical distribution and control cabinets.
- Panel-building and switchboard applications.
