The GRCNSRT Industrial-Grade PV Disconnect Switch is designed for heavy-duty PV systems, RVs, and EV chargers. Built with thickened silver-plated pure copper contacts and a non-polarized design, it ensures maximum conductivity with hassle-free, reversible wiring. For superior protection, it features advanced arc-extinguishing technology, flame-retardant materials, and a padlock design, while the housing delivers IP66 weatherproof durability in harsh outdoor environments.
PV disconnect switches connect or isolate solar arrays and inverters/batteries. They support 1-20kW residential and commercial PV systems and meet the DC-side O&M needs of high-power centralized/string power plants.
