Why Choose the ABB MBA290T XT1/3 Expansion?
The ABB MBA290T is an XT1/XT3 expansion assembly designed for integration into compatible ABB low-voltage subdistribution systems. Supplied under ABB order code 2CPX041644R9999, the MBA290T provides a 2 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 MBA290T provides the system-specific mounting arrangement required to integrate XT1/XT3 circuit-breaker equipment into compatible cabinet configurations. Its coordinated design helps panel builders maintain consistent equipment positioning and an organised internal layout.
The 2 PW format provides a defined installation section for compatible breaker equipment, making the MBA290T suitable for new panel construction, system expansion and distribution-board configurations requiring ABB Tmax XT protection devices.

Structured Integration for ABB Tmax XT Circuit Breakers
Modular expansion assemblies provide the mechanical interface required to incorporate protective devices into structured low-voltage distribution systems. By using a dedicated system component such as the MBA290T, panel builders can integrate compatible Tmax XT circuit breakers while maintaining consistent equipment positioning and cabinet organisation.
The ABB MBA290T is specifically identified for XT1/XT3 equipment and provides a 2 PW expansion section. This makes it a practical choice for compatible ABB distribution assemblies requiring additional moulded-case circuit-breaker capacity without departing from the intended modular cabinet architecture.
