The GM-200 Ground Monitor is pilot wireless, eliminating pilot wire costs, repair and lost downtime. But that is not the only way the GM-200 low voltage, single circuit, continuity ground monitor makes for easy maintenance. For starters, the GM-200’s installation cut-outs are compatible with many of the industry standards, so RETROFITTING on the modular output panels of the power distribution center can usually be done WITHOUT DRILLING ANY HOLES. Furthermore, we have SIMPLIFIED troubleshooting and repairs with our PLUG-IN DESIGN on all assemblies. Even replacing or adding cables requires no calibration.

  • Time delay to reduce nuisance tripping.
  • Solid state design, that is immune to stray currents or induced voltages.
  • Indicator light and test button to easily check the status of the system.
  • Optional ground fault package.
