Square D EDB34060 Bolt On 3 Pole Circuit Breaker

Square D EDB34060 is a 60-amp, three-pole molded‑case circuit breaker in the E‑Frame family, designed for bolt‑on mounting in 480Y/277VAC distribution systems. This EDB series device employs a thermal‑magnetic trip mechanism to protect feeders and branch circuits in three‑phase panels and subpanels. It carries a 60 A rating with a maximum interrupting capacity of 25 kA at 480V (277V systems in related configurations) and accepts 14–6 AWG aluminum or copper conductors on its terminals. The footprint matches standard bolt‑on E‑Frame MCCB installations, with dimensions listed as 4.05 in deep, 5.66 in high, by 2.94 in wide. Applications include industrial motor feeders, distribution feeders, and panelboard circuits in commercial/industrial facilities that operate on 480Y/277VAC three‑phase power. As part of Schneider Electric's Square D line, it is a common choice for bolted‑on protection in legacy and contemporary panels that require a robust, interchangeable 60A 3P breaker compatible with 480V systems.
