Why Choose the ABB MA800A Universal Switch Expansion Module?
The ABB MA800A, order code 2CPX041389R9999, is an unequipped universal switch expansion module designed for ABB CombiLine electrical distribution systems. Part of ABB’s DESUJ Sub Distribution product group, it provides a flexible mounting solution for integrating a universal switching device into commercial and industrial distribution cabinets.
The MA800A is supplied unequipped for the installation of one universal switch, allowing the switching device to be selected according to the requirements of the application. Deep cross beams provide variable adjustment, while equipment is secured using cage nuts, giving panel builders flexibility when configuring compatible switching or circuit-breaking equipment.
With a module height of 4 GU / 600 mm, a panel width of 2 PW / 500 mm and 96 space units, the MA800A provides a usable equipment width of 420 mm and usable depth of 147 mm. It is designed for currents up to 800 A, requires a cabinet depth of at least 275 mm and is intended for installation on an ABB WR mounting frame.
