The brand originated in the United States and has a long history of producing components for commercial, industrial, and residential electrical systems. 3G Electric supplies a range of Square D circuit breakers, enclosures, and related equipment, focusing on the QO, QOB, and QOU series of miniature circuit breakers, as well as L-Frame and Q-Frame enclosures. These products are designed for use in load centers, panelboards, and other distribution equipment. The QO series offers plug-in miniature circuit breakers with ratings from 15 A to 50 A, single- and three-phase configurations, and AC voltage ratings up to 240V. Interrupting ratings range from 10 kA to 22 kA at 120/240V AC, depending on the model. The QOB series provides bolt-on miniature circuit breakers for NQOD panelboards, with similar amperage and voltage ranges. The QOU series includes unit-mount breakers suitable for heating applications. Enclosures include L-Frame (400 A, outdoor, surface-mount) and Q-Frame (225 A, indoor, surface-mount) types, compatible with specific Square D circuit breaker families. These products are built to UL standards and are intended for use in environments requiring reliable overcurrent protection. 3G Electric stocks over 1,300 SKUs of Square D equipment, supporting global procurement with logistics for industrial maintenance, facility upgrades, and new installations. The inventory covers common configurations for plant engineers and maintenance managers specifying replacement or new circuit protection components.
