Feature → Business Impact → Application: The JGX3150FAG uses a three-pole configuration on a JG frame rated for 150 A at 600 Vac, delivering reliable protection for power distribution panels. This enables predictable shutdowns during faults, reducing damage to downstream equipment and minimizing downtime in critical production lines. Application: suitable for control panels and distribution blocks in manufacturing environments. Feature → Business Impact → Application: Fixed thermal with adjustable magnetic trip (T185) provides precise overload and short-circuit protection. This improves coordination with other protective devices, lowers nuisance trips, and supports motor startups with controlled interruption. Application: motor control centers and automated lines that require accurate trip profiles. Feature → Business Impact → Application: High short-circuit withstand ratings—50 kAIC at 600 Vac and 200 kAIC at 240/480 Vac—offer robust fault handling and improved selective coordination. This reduces arc flash exposure and equipment damage during faults in high-current systems. Application: industrial power distribution with heavy fault currents. Feature → Business Impact → Application: Line and load terminals with metric mounting simplify wiring and installation, cutting panel commissioning time and improving reliability of terminations. Application: retrofit or upgrade projects in existing enclosures where space and access are limited. Feature → Business Impact → Application: 80% rated, 50/60 Hz capability and Series G compatibility deliver a compact, compliant protection solution with broad regulatory coverage. Application: industrial facilities pursuing global standards and scalable panel architectures.
