FAQs
The DCG6064UWM is designed for solar PV systems, supporting up to 600 VDC per pole with a 200 A rating and a six-pole configuration. Its NEMA 4X enclosure and 304 stainless steel construction make it ideal for outdoor rooftop and ground-mounted installations, where reliable isolation and corrosion resistance are essential.
This unit accommodates large-diameter conductors with main lug sizes: In/Out(LC) up to 300 kcmil-#6 and In/Out(SR) up to 300 kcmil-#6, enabling fewer terminations and streamlined field wiring for DC feeders in PV systems.
Six poles provide complete isolation for multi-string DC configurations, while the non-fusible design reduces failure modes associated with fuses. The isolated return and grounded lugs enhance clear current pathways, improving arc-safety and allowing rapid maintenance without system-wide shutdowns.
UL 98B, NEC 690 per UL 1741 certifications are incorporated, supporting code-compliant installations and smoother approvals for solar PV projects that require robust protection equipment and outdoor-rated enclosures.
The combination of rugged outdoor durability, reduced maintenance downtime, and streamlined installation with large conductors lowers lifecycle costs. Its compliance certifications and high current handling translate to higher reliability, fewer field faults, and faster project commissioning.
