The Square D EGB34100SA is an E-Frame molded case circuit breaker designed for commercial and industrial electrical distribution systems requiring remote tripping capability and dependable circuit protection. Manufactured by Schneider Electric, this 3-pole, 100A breaker combines thermal-magnetic protection with a factory-installed shunt trip for enhanced safety and automated control applications.

Engineered for installation in Square D NF panelboards, the EGB34100SA utilizes a secure bolt-on mounting configuration and includes aluminum load-side lugs for reliable conductor termination. The integrated shunt trip allows remote opening of the breaker from external control circuits, making it suitable for emergency shutdown systems, fire alarm interfaces, safety interlocks, and building automation applications.

With interrupting ratings of 65kA at 120VAC and 240VAC, and 35kA at 480Y/277VAC, this breaker provides high fault-clearing performance for demanding electrical environments. The breaker also incorporates Visi-Trip technology, allowing maintenance personnel to quickly identify tripped circuits and reduce troubleshooting time.
