The Square D EDB34015 is a 3-pole, 15 A molded-case circuit breaker (E-Frame) built for bolt-on mounting in 480Y/277 VAC three‑phase distribution. It occupies a 1-space width and provides thermal‑magnetic overcurrent protection for industrial panelboards and feeders, with a maximum interrupting rating of 25 kA at 480Y/277 VAC. The model name, EDB34015, denotes 15 A, 3-pole, 480 V class protection; variants exist (EDB34015SA with shunt trip, EDB34015RP returnable package) for specialized needs, while the standard EDB34015 covers typical bolt-on 15 A circuits in three-phase panels.
