Selling Policy 25-000 - Distribution and Control Products and Services
The JGX3100FAG uses a JG frame complete breaker with three poles and line/load terminals, delivering reliable protection in compact spaces. Feature to benefit: fixed thermal + adjustable magnetic trip enables precise coordination and faster response to faults, reducing downtime and equipment wear in panel assemblies. Application context: ideal for control panels and MCCs in manufacturing lines where selective protection and predictable trip behavior matter for uptime. The 100 A rating paired with 600 Vac / 250 Vdc voltage support protects feeders and motors while maintaining compatibility with standard power distribution schemes. The Series G design, 50/60 Hz operation, and 80% rated performance support energy management goals without oversizing equipment. With interrupt ratings up to 50 kAIC at 600 Vac and 200 kAIC at 480/240 Vac, it safeguards critical loads in high fault-current environments. Accessories like high-performance handles and plug-in adapters extend lifecycle and serviceability, reducing maintenance cost. The unit ships with a one-year warranty under Eaton policy, reinforcing total cost of ownership benefits.
