FAQs
DCG2064FXM is designed as a two-pole, fusible DC disconnect rated for 200 A and 600 VDC. It supports large conductor terminations up to 300 kcmil-#6 (LC) and 300 kcmil-#6 (SR), enabling straightforward integration with standard PV arrays and combiner boxes. Ensure mounting on a compatible surface and verify UL 98B/NEC 690 compliance for outdoor use.
Key specs include 600 VDC maximum rating per pole, fusible protection, grounded system with isolated return, and a NEMA 4X enclosure made of 316 stainless steel. These features provide robust arc suppression, water and corrosion resistance, and safe de-energization for maintenance in rooftop or exposed outdoor PV environments.
Yes. The unit adheres to UL 98B and NEC 690 per UL 1741 requirements, with a NEMA 4X enclosure for outdoor use. This alignment helps ensure regulatory compliance, easier inspections, and safer operation in solar installations, particularly where outdoor isolation and reliable disconnection are critical.
It is ideal for solar PV applications, including rooftop arrays and ground-mounted systems requiring a safe, fusible DC disconnect. The two-pole design, 200 A rating, 600 VDC capability, and rugged 316 stainless steel enclosure make it suitable for both commercial and utility-grade PV projects that demand durable isolation and easy maintenance.
With a corrosion-resistant 316 SS enclosure, fusible protection, and isolated return, maintenance intervals are reduced and downtime is minimized.
