Built on Schneider Electric’s E-frame platform, it installs in bolt-on panelboards and compatible enclosures, delivering reliable overcurrent protection for single-phase 2-pole circuits in commercial and industrial distribution networks. It offers an interrupting capacity up to 65 kAIC and is TAA-compliant for federal procurement. The EGB24040 is part of the Square D E-frame family and is designed specifically for 480Y/277V operation, ensuring protection for branch circuits in 480Y/277V installations such as lighting feeders and general power circuits in commercial facilities. When selecting a breaker, verify that the target panel accepts E-frame bolt-on devices and that the circuit load matches the 40 A rating to ensure proper protection and code compliance.
