Why Choose the ABB MA290T XT1/3 Expansion 2PW?
The ABB MA290T, order code 2CPX041417R9999, is a mounted CombiLine N Tmax circuit breaker expansion module designed for ABB electrical sub-distribution systems. Part of the DESUJ Sub Distribution product group, it provides a purpose-designed installation platform for fixed-mounted ABB Tmax XT1 and XT3 moulded-case circuit breakers within professional low-voltage distribution cabinets.
The MA290T has a 2 RE / 300 mm height and a two-panel-width / 500 mm width, providing 48 space units. It is supplied unequipped and can accommodate up to two ABB Tmax XT1 or XT3 circuit breakers, including three- and four-pole configurations, with a generous 449 mm useful width.
Designed for applications with a maximum rated current of 250 A, the MA290T includes a mounting cross beam with M4 slide nuts for secure circuit-breaker installation. Plastic covers with equipment cut-outs, 90-degree press-and-turn closures and a RAL 7035 light-grey finish complete the module, which can be installed on ABB EDF or WR mounting frames in cabinets from 215 mm depth.
