FAQs
The DCG3063FWM supports In/Out wiring from 1/0 to #14 AWG on the main lugs for input, with output wiring in the range of #14 to #4 AWG. It is configured for three circuits and a three-pole fusible arrangement, making it compatible with typical solar PV string connectors and field wiring while maintaining safe, code-compliant isolation during maintenance.
Yes. The unit features a NEMA 4X enclosure made from 304 stainless steel, providing excellent corrosion resistance and weatherproof protection. This makes it well-suited for outdoor solar installations, rooftops, and industrial sites where exposure to moisture, dust, and temperature variation is common, reducing maintenance frequency and downtime.
The DCG3063FWM is certified UL 98B and aligns with NEC 690 per UL 1741 requirements. These certifications support safe operation, proper fault protection, and compliance with solar electrical codes, facilitating smoother project approvals and inspections in commercial and utility-scale PV deployments.
The device is rated for 100 A per pole, with three circuits and a maximum of 600 VDC per pole. It uses fusible protection and provides a grounded, isolated return. These ratings support safe, high-current solar applications and enable reliable isolation for maintenance without compromising system performance.
With a three-pole, fusible configuration and defined input/output wiring ranges, installation becomes more straightforward. The 304 stainless steel NEMA 4X enclosure reduces routing complexity for outdoor PV arrays, and the clearly specified wire sizes help prevent mis-wiring, speeding up commissioning and reducing field errors in complex solar projects.
