The 225 A, four-pole JGS4225FAG switches high fault currents with 18 kAIC at 600 Vac and 85 kAIC at 240 Vac, enabling safe interruption across a wide voltage range and reducing the risk of collateral damage in critical electrical systems. This feature translates to faster fault isolation, lower downtime costs, and improved system reliability in manufacturing lines, data centers, and process controls. The fixed thermal, adjustable magnetic trip (T185) provides precise coordination and selectivity, allowing engineers to tailor protection curves to load schedules and prevent nuisance tripping during startup at varying inrush levels. Line and load terminals with metric mounting hardware simplify panel integration, minimize wiring errors, and shorten installation time, which lowers labor costs and accelerates project schedules. The Series G JG frame supports a complete MCCB solution with a robust four-pole configuration and compatible accessories, enhancing serviceability and future upgrade paths in evolving control architectures. Compliance is reinforced by CE, UL, and CSA certifications, backed by Eaton’s warranty and access to detailed application notes and MOEM selection guides, ensuring confident procurement and long-term total-cost-of-ownership advantages.

FAQs
Mounting is straightforward with the metric hardware supplied for Series G MCCBs. Align the four-pole breaker to the panel rail, secure with the included hardware, and connect line and load terminals per the single-line diagram. Verify panel clearance and ensure correct neutral termination if used in a four-wire system. This approach minimizes installation time and reduces wiring errors in control panels.
The JGS4225FAG is rated for 225 A with a 600 Vac voltage rating. It features a fixed thermal, adjustable magnetic trip (T185) and an interrupt rating of 18 kAIC at 600 Vac, 40 kAIC at 415 Vac, 35 kAIC at 480 Vac, and 85 kAIC at 240 Vac, enabling reliable protection across a range of fault currents and voltages in industrial applications.
Yes. The JGS4225FAG carries UL Listed and CE Marking, along with CSA certification, supporting compliant deployment in North America and international markets. These certifications help streamline procurement, reduce site validation steps, and simplify regulatory adherence in multi-site projects.
This four-pole, 225 A MCCB is ideal for industrial control panels, main feeders, and machine protection in manufacturing, processing, and packaging environments.
