Three-pole protection in the JG frame provides robust three-phase overcurrent protection for demanding industrial loads. This feature delivers a fast, accurate trip response and enables selective coordination across distribution networks, reducing nuisance trips and preserving downstream equipment. Designed for industrial control panels and motor-control centers, it supports reliable operation in manufacturing environments and simplifies panel architecture. Fixed thermal and adjustable magnetic trip (T185) lets you tailor protection to motor inrush and fault currents. This directly improves uptime by avoiding unnecessary trips while still delivering fast interruption during actual faults. Applications include new installations and panel upgrades in conveyors, pumps, and process equipment. 600 Vac rating, 150 A, 50/60 Hz compatibility ensures compatibility with common factory mains. The 80% rated specification supports efficient motor starting and reduces derating in energy distribution schemes. Industrous users rely on precise interrupt ratings—50 kAIC at 600 Vac, 150 kAIC at 480 Vac, and 200 kAIC at 240 Vac—to plan fault current protection. Line and load terminals with metric mounting hardware simplify wiring and mounting, speeding installation and future service. The compact footprint fits tight panel envelopes and supports easy retrofits with compatible MCCB accessories. Certifications include UL Listed, IEC Rated, CSA Certified, and CE Marked, covering global markets. This certification suite reduces compliance risk and accelerates procurement across international projects. Designed for industrial environments, it supports standardization and spare-part compatibility across regions. Compact dimensions (3.57 in depth, 4.13 in height and width) and a 6 lb weight enable dense panel layouts. Wider panels, lower enclosure costs, and easier transport make this MCCB a practical choice for OEMs and system integrators.

FAQs
Installation starts with verifying the panel’s bus rating and ensuring the JG frame MCCB is compatible with the panel’s mounting footprint. Connect line and load conductors to the respective terminals, using metric mounting hardware as specified, and secure the breaker in the rail or panel throat. Check alignment, torque connections to the manufacturer’s recommendations, and verify that the trip unit setting is appropriate for the protective coordination plan. Refer to the Eaton specification sheet and MCCB catalog for wiring diagrams, torque specs, and accessory compatibility to avoid mis-wiring and ensure a clean, safe, and compliant installation.
At 600 Vac, the JGU3150FAG provides an interrupt rating of 50 kAIC, while at 480 Vac it provides 150 kAIC. These ratings indicate the maximum fault current the breaker can interrupt without damage to itself or the system, enabling proper coordination with upstream devices and enhanced protection for downstream equipment. Always verify site fault current calculations and ensure coordination with upstream protective devices to maintain system reliability and safety.
Yes. The JGU3150FAG is UL Listed and CSA Certified, IEC Rated, and CE Marked, which aligns with global regulatory requirements and broadens market eligibility. These certifications support compliance during audits, simplify procurement for multinational projects, and enable standardization across regional facilities. When sourcing MCCBs for global deployments, this certification suite reduces risk and streamlines qualification processes.
Series G MCCBs are suitable for industrial control panels, motor-control centers, and process equipment where reliable overcurrent protection and selective coordination are critical. In addition to protecting three-phase loads up to 150 A at 600 Vac, the devices support quick response to faults, providing protection for conveyors, pumps, and automated manufacturing lines. The metric mounting and line-load terminals also facilitate retrofits in existing installations.
The Eaton policy provides a one-year warranty from the date of installation or eighteen months from the date of shipment, whichever occurs first. This warranty covers manufacturing defects and performance issues within the specified limits. For maintenance considerations and ROI, keep records of installation dates and serial numbers, and coordinate with Eaton’s service centers for approved replacement parts and validated repair options.
