2CPX041768R9999 ABB MBN363 N+PE / Terminal Expansion 3PW

Why Choose the ABB MBN363 N+PE / Terminal Expansion 3PW?

The ABB MBN363 is a CombiLine N N/PE busbar and terminal expansion module kit designed for structured neutral, protective-earth and terminal distribution within low-voltage electrical assemblies. Supplied under ABB order code 2CPX041768R9999, this 3PW module combines a two-pole horizontal N/PE busbar system with additional DIN rails for terminal blocks.

The MBN363 uses ZX149 busbar holders and accommodates a maximum of two copper busbars in a horizontal arrangement. The busbar system is rated up to 630 A, while the three-field-width construction is additionally braced in the centre to provide mechanical support across the wider module. Copper busbars are selected and ordered separately.

With dimensions of 450 × 750 × 260 mm, the MBN363 provides 108 space units and two additional DIN rails for terminal blocks. The DIN-rail mounting depth is continuously adjustable, providing a usable depth of 90–145 mm and a usable terminal width of 688 mm. The module is suitable for cabinets from 275 mm depth.

Key Advantages

• Combines N/PE busbars and terminal mounting in one modular CombiLine N section.
• 3PW / three-field-width configuration provides substantial terminal installation capacity.

Reliable N/PE and Terminal Distribution for Electrical Assemblies

N/PE busbar and terminal modules such as the ABB MBN363 provide a structured location for neutral and protective-earth distribution while also accommodating terminal blocks for circuit connections. Combining these functions within one module helps panel builders create clear, accessible wiring arrangements in professional low-voltage distribution assemblies.

The MBN363 combines a 630 A two-pole busbar system with two additional DIN rails, generous terminal width and continuously adjustable installation depth. Its three-field-width CombiLine N format is particularly suited to assemblies requiring substantial N/PE distribution and terminal capacity within a single modular section.

Typical Applications

• Low-voltage electrical distribution boards.
• Commercial and industrial switchboards.
• Neutral and protective-earth busbar distribution.
• Terminal-block sections for incoming and outgoing circuits.
• Main and sub-distribution assemblies.
• Electrical panel building and system integration.
• ABB CombiLine N interior expansion systems.
