Square D EGB34050 Three-Phase Molded Case Circuit Breaker

The Square D EGB34050 is a three‑pole molded‑case circuit breaker from Square D’s E‑Frame family, designed to protect three‑phase circuits up to 50 A. It is rated for 277/480 V AC and offers a 35 kA interrupting capacity at 480 V, providing robust short‑circuit protection for feeders and subpanels in industrial or commercial power distribution. Built for bolt‑on mounting in compatible Square D enclosures, the EGB34050 uses thermal‑magnetic trip protection to respond to overloads and faults with reliable, code‑compliant performance. This model is suitable for 50‑amp three‑phase circuits in applications such as motor feeders, machine panels, and distribution blocks within commercial or light industrial facilities. As part of the EGB series, it aligns with standard E‑Frame mounting and electrical connection practices, helping maintain consistent protection across an installation.
