316 stainless steel enclosure with a NEMA 4X rating delivers corrosion resistance in outdoor PV sites, reducing maintenance and downtime. This enhances reliability in rooftop and ground-mounted solar installations where weather exposure is a constant challenge. Two-circuit, 30 A, non-fusible and ungrounded design simplifies wiring, lowers installation time, and minimizes fault propagation, making field servicing safer and quicker for technicians. The 1000 VDC system voltage capability supports modern high‑voltage PV strings, enabling fewer intermediate components and easier system expansion in utility-scale projects. Lug capacity of #14-#2 AWG for both lugs and solid returns streamlines terminations, improving inspection readability and reducing termination errors. Certifications UL 98B and NEC 690 per UL 1741 reinforce regulatory compliance, while the 316 stainless steel enclosure provides long-term durability in harsh environments. A robust warranty offers protection against field failures, supporting total cost of ownership (TCO) reduction.
