FAQs

Install the JGS3150FAGB2 in a panel designed for the JG frame Series G MCCBs. Verify line and load terminal orientation per Eaton installation guidelines, secure mounting with the standard mounting footprint, and confirm correct wiring to prevent nuisance trips. Refer to the specification sheet SA012004en for installation sequences and torque values.
Consider the 150 A amperage rating, 600 Vac maximum voltage, and the interrupt ratings of 85 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 18 kAIC at 600 Vac. Ensure the magnetic trip is adjustable (T185) for coordination with upstream protective devices and that the device supports 50/60 Hz operation.
Yes, as a three-pole MCCB with fixed thermal and adjustable magnetic trip, it supports motor feeder protection and overload/short-circuit isolation. Its T185 trip type allows tuning to motor inrush, minimizing nuisance trips while providing rapid fault clearance for motors and drives.
The device is IEC Rated, UL Listed, CSA Certified, and CE Marked, enabling global deployment across regions. These certifications help meet regulatory requirements, streamline supplier qualification, and support cross-border panel builds and OEM programs.
The unit carries Eaton’s standard warranty and is designed for long service life with minimal maintenance when installed per guidelines. Its robust interrupt ratings and compact form factor reduce spare parts, space, and downtime, contributing to a favorable total cost of ownership in panel builds and retrofit projects.
