Quick Summary

Eaton Series G molded case circuit breaker protects industrial power distribution by interrupting fault currents. Engineers often fight nuisance trips, miscoordination, and space constraints that slow startup and increase maintenance costs. This model carries CSA Certified, UL Listed, and CE Marked approvals, supporting safe global deployment. With a 125 A rating at 600 Vac and four poles, it enables robust protection while simplifying panel design and replacement strategies. In practice, it supports metric mounting, 50/60 Hz operation, and 100% protected neutral pole, aligning with common industrial grids. Choosing Series G reduces risk of over-tripping, improves selective coordination, and lowers total cost of ownership through longer service intervals. The integrated four-pole design simplifies wiring, line/load terminals, and protective neutral pole management, speeding installation and commissioning.

Feature: JG frame complete breaker provides a ready-to-install, four-pole solution with line and load terminals integrated. Business Impact: reduces panel fabrication time, minimizes field wiring errors, and lowers commissioning risk in high-mix environments. Application: ideal for control cabinets, machine enclosures, and distribution panels that require reliable protection at 125 A and 600 Vac, with 50/60 Hz operation and metric mounting to fit global panels. The all-in-one design also supports safer neutrals and easier inventory management for service teams. Feature: Adjustable thermal and magnetic trip enables precise protection for a broad range of loads. Business Impact: improves selective coordination, reduces nuisance trips, and extends equipment life by avoiding wrong trip curves. Application: motor feeders, conveyors, and process lines where accurate trip curves are critical and downtime costs are high. Field technicians can tailor the curve to inrush profiles without replacing components. Feature: 100% protected neutral pole along with robust line/load terminals and metric mounting hardware. Business Impact: enhances safety by ensuring balanced neutral protection, simplifies wiring with standardized hardware, and speeds installation in panel builds across facilities. Application: panel boards and switchgear in automotive, food and beverage, packaging, and general manufacturing sectors where consistent neutral protection matters. Feature: High interrupt ratings across voltages—200 kAIC at 240 Vac, 150 kAIC at 480 Vac, and 50 kAIC at 600 Vac. Business Impact: enables reliable fault current handling, reduces upstream damage, and minimizes downtime in the event of short circuits. Application: feeders and drives in harsh industrial environments, including distribution feeders and machine lines that experience peak fault levels. Feature: Series G family integration and broad certifications—CSA Certified, UL Listed, CE Marked. Business Impact: streamlines compliance, simplifies vendor qualification, and supports global deployments with consistent protection performance. Application: OEMs and integrators delivering panel assemblies for international markets, where standards alignment speeds project delivery and reduces risk.

FAQs

Install the JGU9125AAG using its metric mounting hardware and secure line and load terminals. Ensure the four-pole unit is correctly oriented for your panel, verify 50/60 Hz compatibility, and follow the manufacturer’s torque specs for the terminations. With an adjustable thermal-magnetic trip, set the protection curve to match motor inrush and process loads to minimize nuisance trips during commissioning.
The JGU9125AAG is rated for 125 A at 600 Vac, four poles, with adjustable thermal and magnetic trip. It offers interrupt ratings of 200 kAIC at 240 Vac, 150 kAIC at 480 Vac, and 50 kAIC at 600 Vac, operates at 50/60 Hz, and uses line/load terminals with metric mounting. This makes it suitable for demanding industrial panels and machines.
Yes. The four-pole JGU9125AAG with adjustable thermal-magnetic trip is well-suited for motor control panels and feeders. Its Series G design provides robust protection, selective coordination, and 125 A at 600 Vac capability, helping control panels handle motor inrush while protecting circuits from short circuits and overloads.
JGU9125AAG carries CSA Certified, UL Listed, and CE Marked approvals, ensuring compliance for North American and international installations. These certifications support safer procurement decisions, standardize performance expectations across sites, and help simplify regulator reviews during audits.
The JGU9125AAG reduces downtime by improving selective coordination and reducing nuisance trips, while its four-pole, integrated design speeds installation and serviceability. With durable interrupt ratings and a robust neutral pole, maintenance intervals can extend, lowering total cost of ownership for panel builders and end users.
