DC Isolating Switch

Basic Information

Model S32D S32D-T S32D-TL S32D-W1 S32D-W2

Rated current (A) 16, 25, 32

Pole 4P

Application

S32D series DC isolating switch 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. Max voltage is up to 1200V DC. It holds a safe lead among similar products.
