Product highlights
A 4-pole surge arrestor rated for 385V nominal discharge current with a 100kA surge capacity, designed to protect electrical installations from transient overvoltages caused by lightning strikes and switching surges. This device provides simultaneous protection across all four poles, making it ideal for three-phase systems with neutral protection. Suitable for use in main distribution boards, sub-distributions, and equipment protection in commercial, industrial, and residential installations.
