Eaton JGHDC3200FAW PV Guard MCCB - UL 489
Part Number: JGHDC3200FAW
Quick Summary
JGHDC3200FAW PV Guard is a complete molded case circuit breaker for PV solar systems. Engineers often face unreliable DC protection and challenging installation in tight PV arrays. UL 489 certification, 600 Vac and 250 Vdc ratings, and a fixed thermal with adjustable magnetic trip (T185) deliver reliable protection and precise coordination. This solution reduces wiring complexity with terminals omitted, speeds field commissioning, and helps meet NEC/UL requirements while maintaining a compact footprint. For solar developers and industrial facilities, the combination of rugged DC protection and proven Eaton reliability translates into lower downtime and lower total cost of ownership.
