Distribution arresters

UltraSIL fire protection arrester system

Distribution arrester system for reducing risk of wildfires

Eaton’s Cooper Power series UltraSIL fire protection (UFP) arrester system provides superior surge protection while drastically reducing the risk of fire by controlling the energy released during an end-of-life event. The UFP arrester system is a distribution class fire prevention system designed for installation in all common overhead and riser-pole applications up to 27 kV.

  • Significant fire risk reduction: Ideal for preventing wildfires in dry or drought-stricken areas
  • Visual indicator: Signals when the system has an end-of-life event
  • Infinite temporary overvoltage: Reduces failure rate and improves downstream equipment protection
  • Continuity of power: Efficiently isolates from the line during an end-of-life event, maintaining power to downstream equipment
  • Durability: UltraSIL polymer-housing for optimal shedding and superior UV protection
  • Safety: Increased safety to line personnel during circuit re-energizing operation
UFP Arrester System

The UFP arrester system is part of the UltraSIL polymer-housed Evolution distribution-class surge arrester family of products.
