Schneider Electric EDB14020 Circuit Breaker

Schneider Electric's Square D EDB14020 is a 20 A, 1-pole, bolt-on mini circuit breaker in the E-Frame family, rated for 277 VAC with a 25 kA maximum interrupting capacity. Designed for panelboard installations and other distribution applications, it uses bolt-on mounting and accepts 12–14 AWG conductors, making it suitable for typical branch-circuit protection in commercial buildings that run on 277 V. This 1P device is TAA-compliant, ensuring compatibility with government procurement requirements. The EDB14020 is part of Square D's E-Frame bolt-on line and is intended to protect a single 277 V circuit in a distribution system. It is used on 277 V circuits in commercial panelboards requiring straightforward, single-pole protection for dedicated branches. The E-Frame bolt-on design provides a robust, standardized mounting interface across Square D's family of 1-pole breakers, helping align replacement parts across installed panelboards.
