Why Choose the ABB MBA190T XT1/XT3 Expansion 1PW?
The ABB MBA190T is an unassembled CombiLine interior fitting module designed for the installation of ABB Tmax moulded-case circuit breakers within compatible low-voltage distribution cabinets. Supplied under ABB order code 2CPX041643R9999, it forms part of the ABB DESUJ Sub Distribution product group and provides a purpose-designed mounting solution for Tmax XT1 and XT3 circuit breakers.
Designed for fixed-mounted installations, the MBA190T is supplied unequipped and accommodates compatible ABB Tmax XT1 or XT3 MCCBs. It includes a mounting cross beam with M4 slide nuts and a plastic cover with a circuit-breaker cut-out, allowing panel builders to create a secure and organised breaker installation within the CombiLine system.
The MBA190T has a 1-panel-width (1PW) format measuring 300 × 250 mm, equivalent to 2 grid units and 24 space units, with a usable equipment width of 199 mm. It is suitable for a 4-pole busbar system, supports a maximum rated current of 250 A and can be used from a cabinet depth of 120 mm.

Professional Tmax Circuit Breaker Integration
Dedicated circuit-breaker modules provide a structured method of integrating moulded-case circuit breakers into modular low-voltage distribution assemblies. By combining the required mounting hardware and front cover arrangement in a system-specific module, they help panel builders achieve secure equipment positioning and an organised cabinet layout.
The ABB MBA190T is specifically configured for compatible Tmax XT1 and XT3 circuit breakers and provides the mounting cross beam, M4 slide nuts and cut-out cover required for integration into the CombiLine system. The module itself is supplied without a circuit breaker, allowing the appropriate compatible MCCB to be selected for the application.
Typical Applications
- ABB CombiLine low-voltage distribution cabinets.
- Installation of ABB Tmax XT1 and XT3 moulded-case circuit breakers.
- Electrical sub-distribution assemblies.
- Commercial and industrial switchboards.
- Main and feeder circuit protection arrangements.
- Professional panel-building and system integration projects.
