FAQs
The DCG4064FWM is a four-pole, fusible DC disconnect designed for solar PV installations. It provides safe isolation of 600 VDC circuits at up to 200 A, with a 304 stainless steel NEMA 4X enclosure suitable for outdoor or harsh environments. It is commonly used at the point of utility connection or between PV arrays and inverters to ensure safe servicing.
Yes. The device supports large conductors with Main Lug sizes rated In/Out(LC): 300 kcmil-#6 and In/Out(SR): 300 kcmil-#6, enabling robust 300 kcmil to #6 termination for PV system strings. This simplifies wiring for high-current solar DC circuits and reduces the need for multiple smaller-lug terminations.
The DCG4064FWM carries UL 98B and NEC 690 per UL 1741 compliance, with a NEMA 4X enclosure. These certifications confirm safe operation, appropriate protection against environmental factors, and compatibility with solar electrical standards. The NEMA 4X rating is particularly important for outdoor installations and corrosive environments.
Key features include a 304 stainless steel, NEMA 4X enclosure, four-pole grounded design, fusible protection, isolated return, and heavy-duty 200 A rating for 600 VDC. Together, these provide durable protection against weather, ease of installation, and reliable safety during maintenance or fault conditions in solar arrays.
The DCG4064FWM reduces downtime by enabling quick, safe isolation of DC circuits during maintenance while meeting stringent solar industry standards. Its robust enclosure, high current rating, and large-conductor compatibility help minimize replacement costs and inspection time in outdoor PV installations, delivering improved system reliability and long-term operational savings.
