Very hi-energy primary level protection for service entrances and heavy industrial loads.

Surg-Triangle

Up to 1000 KW systems, Category C locations.

The StediWatt SURG’TRIANGLE Series is intended for heavy industrial, primary-level protection. It provides a safe, critical surge path direct to ground and isolates downline Category B environments from heavy surges, storm and utility line hazards. Ideal for hazard-prone areas where critical, system-dependent equipment or expensive downtime risk is a factor. This series is a must to ‘close the gate’ and prevent any serious power surging from entering your facility and sensitive power equipment.
