It carries a 25 kA short-circuit interrupt rating at 480V and provides thermal-magnetic overcurrent protection for distribution panels in commercial and industrial applications. The 20A, 3P device is rated for 480Y/277VAC with bolt-on mounting, and Schneider lists variants such as the EDB34020AABARP (TAA) for optional accessory configurations.
