Fanox SST – Surge Arrester for Critical Applications

The Fanox SST is the premium surge arrester solution for critical infrastructure where the highest level of transient overvoltage protection is required. Using Metal Oxide Varistor (MOV) technology with high energy discharge capacity, the SST is housed in a robust metallic enclosure and includes a surge event counter and failure pre-test function — essential for predictive maintenance programmes.

  • MOV (Metal Oxide Varistor) technology with high energy discharge capacity
  • Thermally protected — safe disconnection on MOV failure
  • Visual fault indication — clear status at a glance
  • Remote signalling of protection status (SCADA/BMS integration)
  • Low voltage protection level (Up) — excellent clamping performance
  • Robust metallic enclosure for harsh environments
  • Surge event counter — tracks cumulative surge activity for maintenance planning
  • Failure pre-test function — predicts MOV degradation before complete failure

The SST is ideal for data centres, hospitals, process control rooms, telecoms infrastructure, and other critical installations where downtime is unacceptable.
