Why Choose the ABB MA190T CombiLine Tmax Circuit Breaker Module?
The ABB MA190T is a CombiLine internal mounting module for ABB Tmax moulded case circuit breakers, designed for compatible low-voltage sub distribution assemblies. Identified by ABB order code 2CPX041120R9999, the module provides a purpose-designed mounting arrangement for a single compatible Tmax XT1 or XT3 circuit breaker.
The MA190T has a nominal module size of 300 mm high × 250 mm wide, corresponding to 2 grid units and 1 panel width, with 24 space units. It provides a usable width of 199 mm and incorporates a cover with a 216 mm cut-out for the installed circuit breaker.
Designed for fixed installation, the module supports compatible ABB Tmax XT1 and XT3 3-pole or 4-pole circuit breakers and has a maximum rated current of 250 A. It includes a mounting cross beam with M4 fixing hardware, while the appropriate ABB EDF or WR mounting frame is ordered separately.

Flexible Tmax MCCB Integration with ABB CombiLine
The ABB CombiLine system provides modular internal installation solutions for building low-voltage distribution assemblies. The MA190T creates a dedicated mounting position for a compatible Tmax XT1 or XT3 moulded case circuit breaker, helping installers integrate higher-current switching and protection equipment into a structured sub distribution system.
Its 2-grid-unit, 1-panel-width format provides a compact installation footprint while accommodating compatible 3-pole and 4-pole breakers up to 250 A. The module includes the required mounting cross beam, while its cut-out cover provides access to the installed breaker and can be finished with suitable cover strips where required.
Typical Applications
- Commercial low-voltage sub distribution assemblies.
- Industrial electrical distribution systems.
- ABB Tmax XT1 and XT3 circuit breaker installations.
- Main and sub-main circuit protection arrangements.
- Building-services electrical distribution.
- ABB CombiLine modular distribution assemblies requiring an MCCB mounting position.
