Eaton JGU3100AAG Molded Case Breaker - UL Listed

Three-pole design with a JG frame provides balanced protection across three-phase circuits, supporting 100 A feeders in compact panel spaces. This configuration reduces wiring complexity, simplifies panel layouts, and improves fault isolation in motor control centers used in manufacturing and process environments. Adjustable thermal and magnetic trip lets you tailor protection to load characteristics and startup currents, decreasing nuisance trips during motor starts and maintaining uptime for critical machinery. Field-adjustable settings enable fine-tuning without exchanging breakers, reducing maintenance cycles and inventory costs. 600 Vac / 250 Vdc ratings, combined with high interrupt ratings of 150 kAIC at 480 Vac, 50 kAIC at 600 Vac, and 200 kAIC at 240 Vac, deliver robust short‑circuit protection in demanding industrial environments. This performance supports reliable equipment protection for power distribution panels and process lines. Line and load terminals simplify field wiring, testing, and future upgrades, while compatibility with Series G accessories expands configuration options for motor starters, modular panels, and control cabinets. The JG frame is designed for straightforward installation in standard electrical enclosures and works with common mounting schemes. UL Listed, IEC Rated, CSA Certified, and CE Marked, this MCCB meets global regulatory requirements, reducing compliance risk for multi‑site deployments. The product lifecycle support includes documented application notes and datasheets that guide tap-rule analysis, terminal sizing, and installation best practices. From a total cost of ownership perspective, the Eaton Series G complete breaker delivers long-term reliability, reduced downtime, and predictable protection for feeders and motor circuits. Designed for maintenance teams and procurement professionals, its availability with 50/60 Hz ratings and standard accessories supports fast turn‑around and spare-part optimization.
