Eaton JGEDC3200FAW PV Guard Solar MCCB - UL 489

Three-pole JG frame design delivers robust overcurrent protection for PV strings and inverters, with a 200 A rating and 35 kAIC interrupt capability at 600 Vac. This arrangement aligns with utility-scale and commercial solar expectations, providing dependable clearing of faults while minimizing damage to downstream equipment. The combination of fixed thermal protection and adjustable magnetic trip enables precise coordination with upstream and downstream devices, reducing miscoordination in dynamic PV energy systems. Trip Type T185 gives fast magnetic response when fault current spikes, while the fixed thermal element handles sustained overcurrent conditions. This dual-stage approach improves selective tripping in multi-string, multi-inverter configurations, helping to maintain system uptime and simplify maintenance planning. The result is fewer unwanted trips and more predictable electrical performance in fluctuating solar generation. Terminals are without terminals, which simplifies wiring topology in compact panels and reduces field assembly variability. Combined with copper wire compatibility, the device supports common conductor sizing and secure connections without collars, speeding installation and reducing torque-related looseness. Installers also gain flexibility when retrofitting existing panels or designing modular solar enclosures. UL 489 certification provides recognized safety compliance for MCCBs in electrical protection and PV applications, and the PVGuard line is designed specifically for solar installations. The unit's JG frame and complete breaker designation ensure compatibility with Eaton and partner panels, easing procurement and stocking for project teams. With a 3-pole configuration, it coordinates with other protection devices in a typical DC-AC PV protection scheme. Physical dimensions of 4.13 in width by 4.13 in height and 3.57 in depth, plus a 6.5 lb weight, support straightforward handling and installation in restricted enclosures. The compact form factor reduces panel size and improves heat management in dense electrical rooms, while its copper wiring capability helps maintain low contact resistance. This design supports faster field wiring, fewer assembly steps, and better reliability in harsh environments. Eaton backs the JGEDC3200FAW with a one-year warranty from installation or eighteen months from shipment, whichever occurs first, aligning with standard MCCB service life expectations. Access to PVGard product aids, technical data sheets, and detailed catalogs further supports design validation, procurement decisions, and project documentation.
