Individual Equipment Suppressors
These devices are intended for single phase 120 to 480 VAC or 5 to 240 VDC circuit applications at locations feeding sensitive/critical equipment. They are unique in that they are designed as a stand-alone surge suppression device and require no special enclosure when used outside an existing enclosure or cabinet. Their compact size make installation a breeze and the warranty is the best in the industry. Now add to all that, dedicated “all mode” protection, and you get a device that defines effective and reliable surge suppression. Units are available with our Frequency Attenuation Network™ or simply the encapsulated Optimal Response Network.

Our Solution: Optimal Protection Network™
To eliminate the destructive effects of both external and internal power-related transients and ensure your systems survive and remain operational, our Optimal Protection Network™ plan consists of a layered defense approach, using patented, proprietary surge protection devices. The devices are strategically placed based on your power, data and telecom systems' specific and unique needs.
What are the advantages of Cascading Surge Protection Devices?
Layer 1: Service Entrance Locations
Surge Protection Devices (SPDs) at service entrance locations suppress high-energy transients to levels that downstream SPDs can eliminate. View Devices »
Layer 2: Distribution Panel Locations
Any transient energy remaining from the service entrance location during power system faults or severe lightning strikes are further reduced or eliminated at distribution panels that have properly-applied SPDs installed. View Devices »
Layer 3: Branch Panel Locations
Protecting branch and sub-panel locations further safeguards mission-critical and high-dollar systems from cumulative transients occurring circuit-to-circuit within those panels. View Devices »
Layer 4: Telecom & Data Circuits
Because extremely low-level transients can damage mission-critical telecom, data and control circuits, protection at all building entry points and selected high-risk internal locations is necessary. View Telecom Devices »
Layer 5: Dedicated Load & Point-of-use Locations
Dedicated and isolated loads are protected to mitigate the adverse effects of cumulative transient damage and close-proximity transient-generating locations. View Point of Use Devices »
Our Optimal Protection Network™ Solution also provides:
Strongest Product Warranty in the Industry
25-Year Product Warranty with free SPD replacements, no strings attached!

Surge Protection According to the IEEE
IEEE Std 1100 (Emerald Book), Section 8.6.4 Premise Electrical Surge Protection:
In addition to surge protective devices installed in the service entrance equipment, it is recommended that additional surge protective devices of listed Category "B" or Category "A", as specified by IEEE Std C62.41-2002, be applied to downstream electrical switchboards and panel boards, and panel boards on secondary or separately derived systems if they support communications, information technology equipment, signaling, television or other form of electronic load equipment.
