Feature: 1. MULTI FUNCTIONS: With photovoltaic array input, primary combination, fast circuit disconnection, lightning protection, anti reverse connection, overload protection and more functions. 2. MAIN USAGE: Protect PV solar panels and inverters, reduce length of connecting cables, optimize system instructions, and could increase output power of PV power generation system. 3. INTIMATE DESIGN: The installation and wiring is simple. Transparent cover can check the status of main switch and lightning arrester. IP66 waterproof flame retardant material is more reliable. 4. SAFETY DEVICE: 63A air circuit breaker provides short circuit fault protection and control combiner box output. Lightning arrester provides lightning protection. 12 pcs separate 10A rated fuses for overload protection. 5. USED FOR: PV grid or off grid solar power generation system, make your solar panel system work reliably and safely, a perfect equipment for outdoor installation and use.
