Ultra-high energy primary level protection for very large service entrances or extreme exterior transient activity.

Bermuda-Triangle

Up to 2500 KW systems in Category C locations.

The SteditWatt BERMUDA-TRIANGLE Series is intended for heavy industrial, primary-level protection. It provides a safe, critical surge path direct to ground and isolates downline Category A and B environments from heavy surges, storm and utility line hazards. Ideal for all hazard-prone areas where critical, system-dependent equipment or expensive downtime risk is a factor. This serious TVSS series is a must to provide a wall of protection and prevent any serious power surging from entering your facility and sensitive power equipment. Protect your Profits!
