The switches are manually operated, multipolar, and provide safety isolation. They are specifically engineered to handle photovoltaic currents, including no critical current, and can operate under double earth fault conditions. The data sheet details the electrical and mechanical characteristics of the switches, including rated insulation voltage, impulse withstand voltage, utilization category, thermal rating, short circuit capacity, and mechanical durability. It also lists available accessories such as direct and external handles, shaft extensions, and bridging bars. The SIRCO PV switches are crucial components in solar power systems, ensuring reliable and safe operation under demanding conditions. The document provides reference numbers for different current ratings: 275A (Ref. 26PV 3026), 315A (Ref: 26PV 3032), 400A (Ref. 26PV 3041), and 500A (Ref. 26PV 3051).
