The Square D EDB34050SA is a three-pole molded case circuit breaker designed for overcurrent protection in three-phase electrical systems, featuring a 50A current rating and a 480Y/277V voltage rating. Its thermal-magnetic protection mechanism provides both long-time and instantaneous trip functions, housed within a compact bolt-on unit measuring 143.76 mm H x 99.57 mm W x 102.87 mm D and weighing 4.178 lb. This breaker is certified to cULus and IEC standards and is engineered for an interrupting capacity of 18kA at 480V, with a maximum ambient temperature rating of 40°C (104°F). It is configured with a 120V shunt trip for remote operation and is typically installed in NF-style panelboards, accommodating wire sizes from AWG 12 to 2/0 for aluminum and AWG 14 to 2/0 for copper conductors via its lug terminals.
