FRS-A series voltage limiting type/ voltage switching type primary power surge protectors are designed according to IEC and EN 61643 standards, and applied to surge protection at the first stage of the power supply system. Products are standard 35mm rail mounting methods.
FRS-A series voltage limiting type/ voltage switching type primary power surge protectors with high flow capacity, single module impact current up to 50KA(10/350s), can prevent all kinds of lighting surge. Products are applies to the power supply of the equipment system in the higher risk area of lighting strike. The first surge protection can be used in single phase/ three-phase power supply line.
*Main power distribution panel in buildings
*Overhead distribution box in buildings
*Outdoor distribution cabinet/ distribution box
