Square D By Schneider Electric EDB34020 Circuit Breaker

Square D by Schneider Electric EDB34020 is a bolt‑on, three‑pole miniature circuit breaker designed for 480Y/277V three‑phase systems. As part of the Square D E‑frame family, this 20A device provides overcurrent protection for feeders and branch circuits in compatible panelboards, with a bolt‑on mounting that secures solid installation in panels that accept E‑frame breakers. The EDB34020 is rated to interrupt up to 18 kA at 480Y/277V AC, supporting reliable protection for commercial or light industrial wiring configurations operating at high voltage. This model is clearly identified as a 3P, 20A breaker suitable for 480Y/277V applications, reinforcing protection across all three phases of the circuit. Its form factor and mounting style are intended for use in Square D/E‑frame bolt‑on installations, making it a direct option for upgrading or replacing breakers in legacy systems that require three‑pole 20‑amp protection at those voltages. Use this breaker when you need dependable, code‑compliant overcurrent protection in a three‑phase 480Y/277V distribution setup, ensuring compatibility with square‑dched panelboards that support E‑frame bolt‑on devices.
