ELR2 Series BXPV-ELR2 DC Isolator Switch


ELR2 Series DC Isolator Switch in plastic enclosure is applied to 1~20KW  residential  or  commercial photovoltaic system, placed between photovoltage modules and inverters. Arcing time is less than 8ms, that keeps solar system more safe. To ensure its stability

and long service life, our products are made by components with optimum quality. Max voltage is up to 1200V DC. It holds a safe lead among similar products.
