Why Choose the ABB MBA194T XT2 4P Expansion Module?
The ABB MBA194T is a CombiLine interior expansion module designed for the installation of one ABB Tmax XT2 4-pole circuit breaker. Supplied under ABB order code 2CPX042906R9999, the module provides a purpose-designed mounting arrangement for integrating an XT2 breaker into compatible low-voltage sub-distribution assemblies.
The MBA194T has a 1 PW field width of 250 mm, a height of 300 mm and provides 24 space units. It is supplied as an unassembled, unpopulated kit and includes a mounting cross beam with M4 slide nuts together with a plastic cover featuring the required breaker cut-out.
Designed for fixed installation of a 4-pole Tmax XT2, the MBA194T supports a maximum rated current of 160 A. It can be used with compatible EDF or WR mounting frames, which are ordered separately, making it a flexible component for professional ABB CombiLine distribution-board construction.

Purpose-Designed Integration for ABB Tmax XT2
The MBA194T provides the mechanical infrastructure required to integrate a 4-pole ABB Tmax XT2 circuit breaker into a compatible CombiLine distribution assembly. Its dedicated breaker cut-out, mounting cross beam and 120 mm usable width create an organised installation position while maintaining the modular layout of the distribution system.
The module is supplied without the circuit breaker and requires a compatible EDF or WR mounting frame to complete the supporting structure. With its 160 A maximum rating and compact 1 PW format, it provides panel builders with a coordinated ABB solution for incorporating XT2 circuit-breaker protection into modular low-voltage assemblies.
Typical Applications
- ABB CombiLine low-voltage distribution assemblies.
- Installation of ABB Tmax XT2 4-pole circuit breakers.
- Commercial sub-distribution boards.
- Industrial electrical distribution panels.
- Modular switchboard construction.
- Professional electrical panel building and system integration.
