Overview
The Schneider Electric EDB34015 is a miniature bolt-on circuit breaker designed for low-voltage panelboard applications. Rated at 15 amperes with 3-pole configuration, this breaker operates at 480Y/277 VAC and offers a maximum interrupting capacity of 25 kA. Built with Square D E-Frame standards, the EDB34015 combines compact design with reliable overload and short-circuit protection for commercial and industrial electrical systems.
Key Features
