The Zforce™ Advantage
Moisture ingress 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 under high pressure for the ultimate seal against moisture.
Zforce™ arresters now feature the same HTV silicone that has been trusted on MPS transmission insulators for over 40 years. This brings the pedigree of our best-in-class aging, contamination and electrical performance to the Zforce arrester line.

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 made of MacLean’s proprietary silicone formulation 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 carefully woven protective fiberglass cage to ensure optimal performance and longevity for each arrester.
Top Stud / Hot Stud
MacLean offers a variety of connector options to suit any application
One Piece Polymer Housing
Our proprietary silicone housing prevents moisture ingress and provides all the excellent UV resistance and contamination performance of MacLean’s transmission insulators.
Composite Reinforced Core
A specialty wound fiberglass weave enshrouds Metal Oxide Varistor (MOV) blocks inside each arrester
Molded Nameplate
MacLean Power Systems is molded into the arrester housing for identification that will last the life of the product
Primed and Bonded End Plug
Both the upper fitting and lower end fitting are primed and bonded with the outer polymer housing to create a single fused protective component
Epoxy Sealed Integrated GLD
The Ground Lead Disconnect (GLD) enables the arrester to remove itself from the circuit at end of life to prevent a short
Insulating Bracket
The robust polymer insulating bracket allows the arrester to be mounted securely in place for normal operation
