The ABB MBA390T is an XT1/XT3 expansion assembly designed for integration into compatible ABB low-voltage subdistribution systems. Supplied under ABB order code 2CPX041645R9999, the MBA390T provides a 3 PW expansion format for incorporating compatible ABB Tmax XT1 and XT3 moulded-case circuit breakers into structured distribution-panel assemblies.
Designed as part of ABB's DESUJ Sub Distribution product group, the MBA390T provides a system-specific expansion solution for compatible XT1/XT3 equipment. Its modular format helps panel builders maintain an organised equipment layout while extending the available circuit-breaker installation capacity within a suitable ABB distribution assembly.
The 3 PW configuration provides a defined installation section for compatible protection equipment, making the MBA390T suitable for new panel construction and distribution-board expansion projects where ABB Tmax XT1 or XT3 devices are specified.
Expansion assemblies allow compatible protective devices to be incorporated into modular low-voltage distribution systems in a structured manner. Using a dedicated system component such as the MBA390T helps panel builders maintain consistent equipment organisation when configuring ABB Tmax XT circuit-breaker sections.
The ABB MBA390T is specifically identified for XT1/XT3 equipment and provides a 3 PW expansion format. This makes it a practical component for compatible ABB distribution assemblies requiring additional circuit-breaker capacity while retaining the intended modular architecture of the subdistribution system.
