Why Choose the ABB MBN362 N+PE / Terminal Expansion 3PW?
The ABB MBN362 is an unassembled N/PE busbar and terminal expansion module designed for ABB CombiLine modular distribution assemblies. Supplied under ABB order code 2CPX041762R9999, it combines a two-pole neutral and protective-earth busbar arrangement with additional DIN rail capacity for terminal blocks.
The MBN362 uses ZX149 busbar holders for a 2-pole horizontal busbar system and accommodates up to two 30 × 10 mm copper busbars. The system has a 92 mm busbar spacing, supports a maximum rated current of 630 A and provides a short-time withstand current of 20 kA.
With a height of 300 mm, width of 750 mm and depth of 260 mm, the MBN362 corresponds to a 2 RE × 3 PW configuration and provides 72 space units. Its 688 mm usable equipment width, adjustable 90–145 mm DIN rail installation depth and additional central support for the three-field-width construction make it well suited to larger N/PE and terminal distribution sections.

Integrated N/PE Distribution and Terminal Mounting
N/PE expansion modules such as the ABB MBN362 combine busbar distribution and terminal mounting within a single modular panel section. The horizontal two-pole busbar arrangement provides infrastructure for neutral and protective-earth distribution, while the additional DIN rail provides structured mounting space for terminal blocks and associated conductor connections.
The ABB CombiLine system uses modular interior components to create configurable distribution assemblies. With a maximum rated current of 630 A, 72 space units, 688 mm usable equipment width and adjustable DIN rail depth, the MBN362 provides a flexible three-field-width solution for integrating N/PE distribution and terminal connections into compatible electrical 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.
