Schneider Electric EDB14050EPD Circuit Breaker

Schneider Electric's Square D EDB14050EPD is a 1-pole molded‑case circuit breaker in the E‑Frame family, rated for 50 A at 277 VAC. Intended for NF panelboards, it incorporates Equipment Protection Device (EPD) ground‑fault protection at 30 mA, rather than a 4–6 mA personnel GFI, delivering equipment‑ground fault protection for the protected circuit. The bolt‑on mounting version is compatible with Square D panels and is specified for up to 18 kA short‑circuit current at 480Y/277 VAC, enabling reliable interruption on higher‑voltage branch circuits. The EDB14050EPD is a single‑pole device, 50 A, 277 V, and is part of the EDB/EPD family; related part numbers include EGB14050EPD and EJB14050EPD for other configurations. This model protects equipment from ground faults while coordinating with upstream protection; ensure your system design aligns with NF panelboard requirements and 277 V distributions. With its 277‑volt rating and 50‑amp capacity, it suits commercial/industrial feeders and branch circuits where equipment protection is mandated and line conditions are 480Y/277 VAC.
