Square D EDB34100 Circuit Breaker

EDB34100 is Square D by Schneider Electric’s 3-phase, 100-amp bolt-on molded-case circuit breaker from the EDB frame family, engineered for 480Y/277 VAC distribution. It provides thermal-magnetic overcurrent protection for feeders and branch circuits in industrial or commercial panelboards, with a short-circuit interrupt rating of 18 kA at 480 VAC and is designed for panelboard installation with bolt-on mounting and standard load-end terminals, and occupies a 3-space width in compatible enclosures. The device’s compact footprint is roughly 2.94 in wide by 4.05 in deep by 5.66 in tall, enabling straightforward replacement in existing E-frame bussing configurations. This 100 A, 3-pole MCCB is part of the Square D EDB series—reliable protection for 480V multi‑panel distributions, motor feeds, and other three‑phase loads in environments where consistent protection and coordination with upstream devices matter. By combining robust thermal-magnetic tripping with a rugged bolt-on mount, the EDB34100 supports rapid, safe fault isolation while maintaining alignment with standard Square D/Schneider Electric panel components.
