Product Detail
AC SPD Surge Protective Device is a three-phase surge protective device that provides surge protection for AC (alternating current) electrical systems. Surge Protective Device SPD AC 3P is designed for protection of three phase AC electrical systems commonly found in commercial and industrial applications. It protects all three phases (L1, L2, L3) of the electrical system. These SPDs use advanced surge protection technologies such as metal oxide varistors (MOV) or gas discharge tubes to absorb and dissipate excess energy of the state voltage spike. These technologies divert energy away from sensitive devices, protecting them from damage. The voltage rating of surge protectors specifies the maximum system voltage they can handle. SPD AC 3P is designed to handle the voltage of a three-phase AC electrical system. Common voltage ratings for three-phase systems include 220V, 380V, 440V, or 480V, depending on specific application requirements.
Description of AC SPD Surge Protective Device:
These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection.
Surge Protective Device SPD AC 3P is installed location are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), ely if the line rounting is external and long.
High energy MOVs equipped with specific thermal disconnectors and related failure indicators.
