Schneider Electric EDB34030 Miniature Circuit Breaker

Schneider Electric's Square D EDB34030 Miniature Circuit Breaker is an E-frame, bolt-on, three-pole MCB rated at 30 A for 480Y/277 VAC three-phase systems, with a maximum interrupting capacity of 25 kA. This bolted-in device is designed for industrial and commercial panelboards that accept E-frame breakers, providing overcurrent protection for feeders and branch circuits in 480Y/277 VAC distribution. The EDB34030 belongs to the Square D E-frame family, delivering rugged construction and consistent trip performance, and it carries a government-friendly bolt-on design (TAA). The model’s three-pole configuration protects all three phases of a 3P system, making it suitable for three-phase distribution equipment, MCCs, and switchgear installations that require a 30 A breaker in a 480Y/277 VAC footprint. Users should verify that their panel supports E-frame bolt-on units and that the installation adheres to applicable electrical codes and listing requirements.
