Feature: 316 stainless steel enclosure with NEMA 4X rating provides weatherproof, corrosion-resistant protection. Business Impact: Extends service life in outdoor or harsh environments, reducing maintenance frequency and downtime. Application: Ideal for outdoor solar installations on rooftops or ground-mounted PV arrays. Feature: 200 A amperage rating with two circuits supports higher DC currents and selective shutdowns. Business Impact: Enables safer, efficient isolation of multi-string PV configurations, improving system reliability and safety margins. Application: Solar projects requiring robust DC disconnects for two-string or multi-string layouts. Feature: Non-fusible protection with isolated return and grounded design. Business Impact: Simplifies protection schemes, minimizes fault paths, and enhances fault isolation and safety compliance. Application: DC photovoltaic systems demanding reliable isolation without fuses. Feature: Wide main-lug wire size compatibility (LC, SR, EG ranges up to 300 kcmil-#6 / 1/0-#14). Business Impact: Reduces field termination constraints, accelerates installation, and lowers pre-wire inventory. Application: Installations with a mix of large feeder conductors and small control wiring. Feature: 1000 VDC system voltage rating and UL 98B/NEC 690 compliance. Business Impact: Ensures regulatory alignment, safer operation, and easier commissioning. Application: Solar PV systems meeting common industry and utility requirements. Feature: Robust dimensions and weight (57.47 in L x 24.12 in W x 12.43 in H; 60 lb). Business Impact: Manageable footprint for retrofit or new builds, simpler mounting, and predictable handling during installation. Application: Enclosures integrated into compact or space-constrained solar installations.
