FAQs

The JGU4225FAG is designed for Series G molded case protection with a four-pole JG frame and metric mounting hardware. It fits standard control panels and switchgear assemblies that accept MCCBs with line and load terminals. For optimal results, verify panel clearance, hot-spot risk, and compatible busbar sizing, then follow Eaton installation instructions for mounting orientation and torque specifications.
Key specs include a 225 A amperage rating, 600 Vac voltage rating, and interrupt ratings of 200 kAIC at 240 Vac, 150 kAIC at 480 Vac, and 50 kAIC at 600 Vac. The device uses a fixed thermal and adjustable magnetic trip (T185) and is a four-pole MCCB designed for reliable protection in industrial systems.
Yes. The JGU4225FAG supports 50/60 Hz operation and is rated for 600 Vac systems. Its four-pole design and line/load terminals facilitate integration in 600 Vac control panels and motor control centers, while the 50/60 Hz compatibility ensures consistent performance across regional power standards.
The JGU4225FAG is IEC Rated, CSA Certified, and UL Listed, with CE Marking also noted. These certifications confirm conformity with international safety and performance standards, easing regulatory approvals, improving supplier confidence, and supporting global deployment in mixed-standards environments.
Expect reduced downtime through reliable fault interruption and predictable trip behavior (T185), plus potentially lower maintenance costs due to solid-state coordination within Series G. The unit’s durable construction, metric mounting, and warranty terms (one year or 18 months from shipment) contribute to long-term total cost of ownership savings in enterprise installations.
