The Zforce™ Advantage

Moisture is the number one reason for conventional arrester failure, which significantly increases maintenance costs.

Our Zero Air Interface polymer housing is molded directly on the composite reinforced core for the ultimate seal against moisture.

Optimized Design Inside and Out

Each component of our Z-force™ arresters has been engineered for optimal surge protection performance.

Inside the water-tight outer shell resides a reliable configuration of Metal Oxide Varistor (MOV) blocks designed to meet your specified electric surge protection range. The MOV blocks are encased in a proprietary protective fiberglass woven shroud to ensure  optimal performance and longevity for each arrester.
