The Square D EGB34050SA is an E-Frame molded case circuit breaker designed for commercial and industrial power distribution systems requiring reliable protection and remote disconnect capability. Manufactured by Schneider Electric, this 3-pole, 50A breaker provides dependable thermal-magnetic protection for overload and short-circuit conditions in three-phase electrical applications.

This model includes a factory-installed shunt trip mechanism, enabling remote tripping for emergency shutdown systems, control automation, and facility safety applications. It is designed for secure bolt-on installation in standard NF panelboards and features load-side lugs for straightforward integration.

With a high interrupting rating of 65kA at 240VAC and 35kA at 480Y/277VAC, the EGB34050SA delivers strong fault-clearing performance for demanding electrical environments. A built-in visual trip indicator enhances maintenance efficiency by allowing quick identification of tripped circuits.
