Feature: 400 A amperage rating with a three-pole design enables robust current handling and predictable fault isolation, reducing the risk of overload on each leg. Business Impact: This capability minimizes conductor heating, improves efficiency, and simplifies protective coordination with upstream protective devices. Application: Well-suited for large solar PV strings, utility-scale DC feeds, and battery storage interconnections where dependable current capacity is mandatory. Feature: NEMA 4-rated enclosure in painted galvanized steel provides weatherproof protection. Business Impact: It withstands rain, dust, and washdown environments, lowering maintenance costs and extending service life. Application: Outdoor rooftops, combiner rooms, and harsh industrial sites where protective enclosures are required. Feature: Fusible protection with isolated return. Business Impact: Overcurrent protection and safe fault isolation reduce arc-flash risk and support regulatory compliance. Application: Solar DC disconnects used in PV arrays requiring safe de-energization during maintenance. Feature: In/Out LC and SR wiring options with large conductor sizes. Business Impact: Simplifies field wiring, reduces labor, and enables rapid commissioning with direct terminations. Application: Large-diameter conductors such as 750 MCM-1/0 and 600 MCM-#2 feeding main DC circuits. Feature: UL Listed and rugged construction with clear documentation. Business Impact: Facilitates regulatory acceptance, supplier qualification, and streamlined procurement. Application: Projects in North America and other UL-adopting regions needing certified DC protection equipment. Warranty: One year from installation or eighteen months from shipment, whichever comes first.
