Quick Summary

Eaton JGS3175FAGB2 molded case circuit breaker protects critical loads in industrial control panels and power distribution systems. Downtime from nuisance trips and protection miscoordination is a frequent challenge in busy facilities, especially where panel protection isn’t tuned to the load profile. While this data set specifies 'Compliances: Contact Manufacturer,' the design aligns with Series G MCCB configurations and standard installation practices to support straightforward cross-coordination with upstream devices. With a 175 A rating and a high interrupt capacity, it delivers safety and reliability in 600 Vac environments, helping reduce unplanned outages. This solution also supports easy procurement, consistent spare parts, and robust service from Eaton, aligning with strict maintenance and uptime goals.
