MicroMax GPS350 Current Interrupter

Ensure corrosion mitigation effectiveness and meet regulatory requirements

The MicroMax GPS350 is a portable, flexible, rugged, fully-programmable GPS synchronized current interrupter that is designed specifically for cathodic protection (CP) surveys. It is the smallest interrupter available with a built-in solid-state relay, keypad, and LCD display and is designed to fit inside most rectifier cabinets. Its patented Interference and Influence technology uses synchronized waveform capture to interrupt hundreds of rectifiers at once sequentially to isolate sources, providing critical data to ensure equipment health.  This device provides current interruption for:

  • Cathodic protection
  • Rectifiers and foreign/critical bonds
  • Measuring On and Instant Off potentials
  • Interference influence of adjacent CP systems

Why Choose the GPS350?

  • Portable –The GPS350 is the smallest interrupter available with a built-in relay, keypad, and LCD display. It is light, weighing about 3 pounds, but rugged enough to withstand the harshest conditions.
  • Compact – The unit is small enough to fit inside many rectifier enclosures or magnetically clamp to the bottom, reducing the chances of vandalism and eliminating the need to chain it down to prevent theft.
  • Flexible – The GPS350 can interrupt either AC or DC, up to 60 A with on/off cycles of less than 4 seconds, and 80 A with cycles totaling 4 seconds or longer. Installation is easy as polarity is not a concern.
  • Transient Voltage Suppression – The GPS350 contains a unique voltage suppression technology that absorbs the inductive energy released during on/off switching and allows the relay to switch much higher currents than previously available.
  • Complete Isolation – The built-in relay is optically driven, ensuring that the interrupter is isolated from high energy events such as lightning strikes.
  • Isolate Sources of Influence and Interference – Patented Interference and Influence technology uses synchronized waveform capture to interrupt hundreds of rectifiers at once sequentially to isolate sources, providing critical data to ensure equipment health and develop an informed mitigation plan.
