FAQs
Installation starts with confirming the panel accepts metric mounting components and three-pole clearance. Mount the JG frame breaker using the supplied metric hardware, connect line and load terminals per the enclosure diagram, and torque terminals to Eaton’s specifications. Verify the trip setting (T185) and ensure the unit sits squarely within available slots for proper safety clearance and qualified service access.
Key specs include a 250 A amperage rating, 600 Vac voltage rating, and three-pole configuration. The interrupt ratings vary by voltage: 85 kAIC at 240V, 40 kAIC at 415V, 18 kAIC at 600V, and 35 kAIC at 480V. The trip type is T185, with fixed thermal and adjustable magnetic trip for tailored protection in your load profile.
Yes. The three-pole design, high interrupt ratings, and Series G compatibility make it ideal for motor control centers and machine feeders. Its fixed thermal, adjustable magnetic trip provides selective coordination, helping to protect critical motors while avoiding unnecessary trips during startup or transient faults.
The JGS3250FAG is CE Marked, UL Listed, and CSA Certified, aligning with global safety and performance requirements. These certifications support compliance across international sites and simplify procurement for multi-country projects, reducing regulatory risk during audits and site installations.
Expect improved uptime due to reliable fault interruption and precise trip coordination, which minimizes unplanned outages. The metric mounting and modular Series G design simplify retrofits and spare-part stocking, lowering maintenance labor costs. Over the life of the panel, this translates to reduced downtime, predictable service intervals, and a favorable total cost of ownership.
