Our surge protection products ensure your remote monitoring units and rectifiers are safe from electrical surge events:

  • High Energy Surge Arrester: Designed with a full 40kA surge capability, 4X the level of traditional secondary surge arresters.
  • SurgeFuse: When a surge event exceeds the arrester’s capabilities, it intentionally breaks to stop the electrical current.
  • SurgeDetector: Detects and logs high energy surge events. Track surge events over time using remote monitors and Bullhorn Web.

Use individually or together to keep your equipment operational with less downtime.

Solid State Relays

Our solid-state relays are built to withstand the elements, and optimized for cathodic protection applications.

Plus, AI's unique Transient Voltage Supression (TVS) technology allows relays to switch higher currents than similar products on the market. 

AI's solid state relays are:

  • Small enough to fit inside most rectifiers
  • Compatible with MicroMax Current Interrupters and interruption-enabled Bullhorn Remote Monitors
  • Maintain impressed current for cathodic protection, even if the interrupter loses power
  • Longer lasting than Mercury devices
  • Available in multiple configurations
