Eaton JGHDC3100FAG PV Guard complete MCCB - UL 489
Part Number: JGHDC3100FAG
Quick Summary
Eaton PV Guard complete molded case circuit breaker is a DC/PV protection solution for solar installations. This model delivers reliable overcurrent protection for 100 A circuits while handling 600 Vac and 250 Vdc in compact enclosures. Operators often struggle with nuisance trips, space constraints, and wiring complexity in PV cabinets; JGHDC3100FAG addresses these with a three-pole, line-and-load device featuring fixed thermal and adjustable magnetic trip (T185) in a compact JG frame. The product complies with UL 489 and supports a wide 50/60 Hz environment, aligning with industry safety expectations. In practice, it enables faster commissioning, lower total cost of ownership, and improved system uptime by coordinating with Eaton PVGard accessories.
