Schneider Electric EDB34015 Three-Phase Circuit Breaker

Schneider Electric’s Square D EDB34015 is a bolt‑on, three‑pole molded‑case circuit breaker rated at 15 A for 480Y/277 VAC three‑phase service. As part of the EDB family, this bolt‑on, E‑frame device delivers an 18 kA interrupting capacity at 480 VAC (and up to 25 kA at 240 VAC) and accepts 14–6 AWG aluminum or copper conductors. The thermal‑magnetic trip mechanism provides overload and short‑circuit protection for three‑phase circuits, making it suitable for guarding motors, pumps, and other equipment in commercial or light‑industrial panelboards powered from 480 VAC systems. Designed for use with compatible Square D/Schneider Electric panels, it helps ensure proper mounting and coordination across three‑phase distribution. In practice, this 3P, 15 A breaker is used to protect branch circuits in industrial or commercial applications that run on 480Y/277 VAC, delivering reliable, coordinated protection for each phase while maintaining a compact, bolt‑on form factor for straightforward replacement in suitable enclosures.
