Appearance Introduction

BYH Series DC Isolator Switch in plast ic enclosure is

applied 1~20KW Residential or Commercial Photovoltaic system, placed between

photovoltage modules and inverters. Arcing time less than 3ms, that keep solar

system more safe. To ensure its stability and long service life, our products are

made by components with optimum quality. Max voltage up to 1000V DC It holds a

safe lead among similar products.
