Schneider Electric EJB34030 Bolt-On Circuit Breaker

Schneider Electric EJB34030 is a three-pole, 30-amp miniature circuit breaker in the E-Frame bolt-on family, designed for secure mounting in compatible Schneider Electric panel enclosures that accept bolt-on breakers. It is rated for 480Y/277 VAC three-phase systems and provides overcurrent protection with a maximum interrupting capacity of 100 kAIC, enabling fast fault interruption in demanding electrical distributions. The bolt-on E-Frame design simplifies installation by allowing direct attachment to the panel structure, while the unit is identified as Trade Agreements Act (TAA) compliant. This 30 A device protects three-phase feeder circuits in commercial and light industrial facilities, including equipment such as motors and HVAC systems that operate on 480Y/277 VAC. Terminations accommodate standard conductors used in Schneider Electric installations, and the EJB34030 sits within the Square D EJB lineup of bolton breakers designed for reliability and consistent performance in Schneider panels. Bolt-on mounting and E-frame construction align with Schneider Electric's standard for modular, field-installable protection in distribution panels.
