Schneider Electric EGB34100 Molded Case Circuit Breaker

Schneider Electric's EGB34100 is a three-pole molded-case circuit breaker (E-Frame) rated at 100 A for 480Y/277 VAC three-phase power systems. This bolt-on MCCB provides thermal-magnetic overcurrent protection and has a maximum interrupting capacity of 65 kA at 480 V. The unit is TAA-compliant, making it suitable for equipment stocked in regions requiring Trade Agreements Act compliance. Part of the Square D EGB family, the EGB34100 is designed for use in panelboards and enclosures that accept EGB-type breakers, delivering coordinated protection across all three phases. The 3P configuration helps protect three-phase feeders and distribution circuits in commercial and industrial installations powered from 480 V nominal supplies. As with all EGB devices, proper installation requires matching lugs and accessories specified for EGB MCCBs and adherence to Schneider Electric's mounting and wiring guidelines. The model is identified by the part number EGB34100 and is widely cataloged by distributors and integrators that align with Schneider Electric's Square D lineup.
