Three-pole design delivers 150 A with 600 Vac and 250 Vdc ratings, enabling simultaneous protection of AC and PV circuits. This alignment reduces the need for separate devices, lowering panel footprint and installation time. It is particularly beneficial in large solar installations where phase balance and source protection must be maintained across inverters, combiner boxes, and switchgear. Trip Type T185 with fixed thermal and adjustable magnetic functions provides precise fault isolation. Business impact: minimizes nuisance trips during switching transients while preserving selective coordination with upstream protections. Application: protects three-phase PV systems in arrays and inverters, improving uptime and reducing maintenance costs. Interrupt rating of 35 kAIC at 600 Vac enables rapid interruption of high fault currents in commercial and utility-scale PV plants. This UL 489-listed device ensures compliance with safety standards and reduces arc energy exposure, supporting utility and code requirements. Application: critical in service entrances, PV combiner panels, and on-utility feeder protection in solar facilities. JG frame compatibility offers seamless integration into Eaton PVGard ecosystems and existing MCCB inventories. Business impact: simplifies stocking, reduces engineering risk, and accelerates panel assembly. Terminals: Without terminals means you attach the proper lugs or connectors to suit wire gauges and enclosure constraints, providing installation flexibility across diverse solar configurations. Compact footprint—3.57 in depth, 4.13 in height and width, and approximately 6.5 lb weight—helps save enclosure space and improve OSHA-friendly layouts. The combination of small size with high interrupt capability supports densely packed PV protection panels and easier serviceability, while maintaining robust protection of both DC and AC circuits in a single device. UL 489 listing reinforces ongoing compliance and safety for industrial solar protection.

FAQs
The JGEDC3150FAW should be installed in an enclosure that supports the JG frame and three-pole breaker configuration. Mount in line with Eaton's protection scheme, connect conductors using compatible lugs (terminals are not included), and torque connections per manufacturer guidelines. Always refer to PVGard product aids and the MCCB catalog for wiring diagrams.
The JGEDC3150FAW has a 35 kAIC interrupt rating at 600 Vac, which defines the maximum fault current the MCCB can interrupt safely. In PV installations, fault currents can be high, so this capability protects wiring and components, helps meet utility and code requirements, and minimizes the risk of cascading faults. It also supports better coordination with upstream protections.
Yes. The device is rated for 600 Vac and 250 Vdc, enabling protection of both AC mains and DC PV strings within a single three-pole MCCB. This makes it a versatile choice for PV protection in inverters, combiner boxes, and switchgear, while maintaining proper safety margins and code alignment.
The JGEDC3150FAW is UL 489 listed, which confirms compliance with recognized safety standards for molded case circuit breakers. This certification supports regulatory compliance, enables safer operation in commercial and industrial PV installations, and helps installers meet NEC and local electrical codes when protecting PV systems.
The device measures 3.57 inches in depth, 4.13 inches in height and width, and weighs 6.5 pounds. It is without terminals, so you must select compatible lugs or connectors for your wire gauges. Plan enclosure space accordingly to maintain adequate clearance and ensure straightforward integration with existing Eaton PVGard assets.
