Square D EDB14050EPD is a molded case circuit breaker designed for ground fault equipment protection in industrial and commercial electrical systems. It provides a 50A current rating with a 277V AC voltage rating and features a thermal magnetic trip mechanism with long-time and instantaneous (LI) functions for reliable overload and short-circuit protection. The single-pole, bolt-on breaker is constructed within a compact 125A/EDB frame, measuring 168.66 mm H x 49.78 mm W x 102.87 mm D and weighing 2.1 lb, and utilizes lug terminals compatible with copper wire from 14 to 6 AWG and aluminum wire from 12 to 4 AWG. It is certified to cULus and IEC standards for safety and performance, with an interrupting capacity of 18kA at 480V, and is rated for operation in environments up to 40°C (104°F). This breaker is typically applied in 1-phase NF panelboards for branch circuit protection where ground fault detection is required.
