Schneider Electric EGB34050 Miniature Circuit Breaker

Schneider Electric's Square D EGB34050 Miniature Circuit Breaker is a three-pole, 50 A E-frame bolt-on circuit breaker designed for 480Y/277 VAC panelboards. It offers up to 65 kA interrupt capacity at 480Y/277 VAC, enabling robust protection for circuits that can experience high fault currents in commercial installations. The EGB34050 is built for bolt-on mounting in compatible panelboards and is part of Schneider Electric’s E-frame family, which is known for mechanical compatibility across devices. Rated for 480Y/277 VAC and three-phase operation, this unit is commonly used to protect lighting panels and other distribution circuits in commercial or light industrial facilities. The 50 A rating makes it suitable for feeders and branch circuits where medium-size protection is required, and its Square D lineage ensures alignment with other E-frame breakers for straightforward replacement within the same system. This part number is widely cataloged under Schneider Electric’s Square D line and is designed to deliver reliable protection in panelboard systems that require bolt-on installation and a high short-circuit current rating.
