FAQs
The JGS3100FAGC is designed for Series G molded case sections with the JG frame and three-pole configuration. Install with copper line and load terminals, verify torque per Eaton specs, and align with the panel’s bus bar layout. Its fixed thermal and adjustable magnetic trip simplify field settings during commissioning and ensure proper coordination with nearby protective devices.
The breaker offers 85 kAIC at 240 Vac, 18 kAIC at 600 Vac, and 35 kAIC at 480 Vac, with a voltage rating of 600 Vac and 250 Vdc. These ratings support high-energy feeders and mixed-energy systems typical in industrial facilities, enabling safer operation and faster fault clearance.
Yes. With three-pole configuration, Series G design, and a T185 trip type (fixed thermal, adjustable magnetic), it coordinates well with motor starters and drives, protecting motors from overcurrent while minimizing nuisance trips during startup and load changes.
The JGS3100FAGC is IEC Rated, UL Listed, and CSA Certified, with CE marking. These certifications support global compliance, simplify purchasing for multinational projects, and provide auditable safety assurances for regulated environments.
With a one-year Eaton warranty (policy 25-000) and standard Series G accessories, maintenance focuses on periodic contact inspection, torque checks on terminals, and trip setting verification during preventative service. The modular design supports straightforward component swaps and minimizes downtime during replacements.
