The 250 A, 600 Vac rating on a three-pole JG frame provides robust protection for high-current loads in industrial panels, enabling reliable machine operation and reduced risk of equipment damage. This translates to fewer nuisance trips and improved process stability, which directly lowers downtime costs in manufacturing lines and critical automation applications. The fixed thermal trip paired with an adjustable magnetic trip (T185) enhances protection coordination, enabling selective tripping and smoother motor startups in demanding environments. Line and load terminals with metric mounting hardware simplify installation, enabling quicker panel integration and compatibility with other Series G components. The MCCB’s 100% rated performance and high interrupt ratings—200 kAIC at 240 Vac, 150 kAIC at 480 Vac, and 50 kAIC at 600 Vac—provide a robust safety margin for high-energy circuits in switchgear and distribution cabinets. Certifications such as CE, UL Listed, IEC Rated, and CSA Certified streamline global compliance and documentation. With compact dimensions (3.57 in depth, 4.13 in height and width) and a weight around 6 lb, installation and serviceability are straightforward, reducing total cost of ownership for panel builders and automation integrators.

FAQs
The JGU3250FAGC uses a metric mounting system and a JG frame, designed for straightforward replacement in modern switchgear and control panels. It supports line and load terminations, fits standard Eaton Series G footprints, and aligns with common panel layouts for quick retrofit or new installations. Ensure panel bus ratings meet the 600 Vac, 250 A specifications and that mounting clearance permits the 3.57 in depth.
The combination provides precise protection coordination: the fixed thermal trip handles sustained overcurrent while the adjustable magnetic trip responds quickly to short circuits. This reduces nuisance trips during motor starting and surge events, improving uptime and extending equipment life. It also supports selective coordination with upstream protections in complex automation systems.
Yes, the JGU3250FAGC is rated for 600 Vac operation. It offers interrupt ratings of 200 kAIC at 240 Vac, 150 kAIC at 480 Vac, and 50 kAIC at 600 Vac, delivering a robust safety margin for high-energy circuits in distribution cabinets, switchgear, and control panels within industrial facilities.
This breaker is CE marked, IEC rated, and UL listed, with CSA certification also documented. These certifications simplify regulatory approvals, enable use across international sites, and facilitate documentation for quality systems and supplier qualification in global manufacturing environments.
The unit’s 100% rated performance, solid interrupt capacities, and reliable Series G design reduce unplanned downtime and maintenance frequency. Its modular compatibility with other Series G components simplifies stocking and service, while the standard warranty (Eaton Selling Policy 25-000) provides coverage to minimize lifecycle risk and total cost of ownership for panel builders and automation integrators.
