AC 3A-32A Ground Continuity Tester.

The GCT-630 is a special purpose safety tester focused only on Ground Continuity testing. When resistance is under measurement, over current protection can be set from 3A to 32A with a ±10% threshold. The dual meters monitor both testing current and resistance in real-time. The GCT-630 has settable alarms with the ability to stop or continue tests.

 

  • AC 32 Amperes High Test Current
  • Measuring Resistance 0 ~ 0.6Ω
  • Continue and Normal Test Mode
  • 4 Wire Measurement
  • GO-NOGO Function
  • Test and Result Output Signal
