Why Choose the ABB ED250T3 XT1-3 Expansion Plate?
The ABB ED250T3 is a 1 panel-width (1PW) combination set designed for the installation of ABB Tmax moulded-case circuit breakers within compatible electrical distribution cabinets. Mounted on the ABB EDF profile system, it provides an unequipped internal expansion field for Tmax XT1 and XT3 circuit breakers.
The ED250T3 has a 2 grid-unit (2GU) configuration measuring 300 mm high × 250 mm wide and providing 24 space units (PLE). Its sheet-steel mounting plate can be continuously adjusted in depth, while plastic covers with 90° push-turn fasteners provide a coordinated finished installation.
Suitable for compatible cabinets from 200 mm depth, the ED250T3 can accommodate Tmax XT1 circuit breakers in 3- and 4-pole configurations and Tmax XT3 circuit breakers in 3- and 4-pole configurations. EDF profile rails and field connectors are included for integration with compatible ABB distribution panels.
