Product highlights
The 4-Pole Surge Arrestor is a Schenker surge protection device rated for 20kA at 275V UC, designed to protect three-phase electrical systems and equipment from transient overvoltages caused by lightning strikes and switching surges. With a 4-pole configuration, it provides simultaneous protection across all phases plus neutral, making it essential for industrial and commercial installations requiring robust surge suppression. Ideal for panel protection, motor circuits, and sensitive electronic equipment in South African electrical installations.
