Schneider Electric EDB34030 Bolt On Circuit Breaker

Schneider Electric's Square D EDB34030 bolt-on, three-pole molded-case circuit breaker (E-frame) is a 30 A device designed for 480Y/277 VAC service, offering a 25 kA maximum interrupting capacity. It employs a thermal-magnetic trip mechanism for reliable overcurrent protection and is intended for bolt-on mounting in compatible E-frame panelboards and switchgear, enabling straightforward installation and field replacement. This 3-pole breaker protects feeders and branch circuits in high-voltage distribution networks, making it a common choice in commercial and industrial applications where 480 V distribution is encountered. As part of the EDB family, the EDB34030's bolt-on format and standard mounting hardware support consistent performance across Schneider Electric’s protection suite, allowing easy cross-reference and integration with other E-frame breakers in the same distribution system.
