Eaton LGEDC3630NN PVGuard Solar MCCB - UL 489
Part Number: LGEDC3630NN
Quick Summary
Eaton LGEDC3630NN PVGuard solar MCCB protects DC PV networks with reliable overcurrent protection. Engineers often wrestle with selecting a high-capacity breaker that withstands rapidly changing PV voltages without nuisance trips or overheating. UL 489 certification underpins safety, and the LG frame compatibility supports smooth integration with existing MCCB infrastructure. Designed as a frame-only, three-pole unit, it delivers 630 A at 600 Vac with 65 kAIC at 240 Vac and 35 kAIC at 415/480 Vac, while 18 kAIC at 600 Vac captures fast fault clearing. The PVGuard branding emphasizes dedicated solar protection, while the compact 5.48 in form factor and absence of terminals reduce field wiring and installation time, translating to lower total cost of ownership in PV system protection.
