GDKC-6A Circuit Breaker Tester

High Voltage Circuit Breaker Tester
  • High Voltage Circuit Breaker Tester
  • High Voltage Circuit Breaker Tester

General introduction

GDKC-6A Circuit Breaker Tester is used to test the dynamic characteristics of high voltage and low voltage circuit breaker. It has features easier operation and higher accuracy comparing to traditional device.


  • 5.7inch touch screen.
  • Thermal printer.
  • 6 channels contacts,1channel velocity test
  • Test 1channel current of CLOSE/OPEN coil.
  • In Routine test, CLOSE-OPEN time, bounce Time, synchronization time can be tested.Also CLOSE-OPEN velocity, Max.velocity, average velocity, stoke distance, over-travel, total travel can be measured.
  • In reclosing test, OPEN-CLOSE,CLOSE-OPEN,OPEN-CLOSE-OPEN time can be tested.
  • In Low-voltage test, Voltage Operate value of CLOSE-OPEN coil can be tested. Power supply voltage can be adjusted continuously.
  • Three kinds of CLOSE-OPEN control modes.
  • Internal Control. Inner power supply will supply DC voltage with CLOSE-OPEN coil.
    External Control. External power supply will supply AC voltage with CLOSE-OPEN coil.
    Idle contact Control. Built-in 2channels passive idle contacts.
  • Contact status-Time curve, Travel-Time(S-t) curve, Coil current-Time(I-t) curve can be recorded. It is convenient to determine fault of circuit breaker.
  • USB interface for connecting with PC.
  • EXCEL format data can be exported.
  • With dustproof and waterproof sealed plastic carry case.
