GDAS-500 DC Circuit Breaker Test Set

General introduction

Circuit Breakers are one of the critical “safety-valves” of electrical systems and basic maintenance procedures are essential to maintain maximum reliability.

This instrument is designed for testing DC circuit breakers at rated current of 1A-500A. It is suitable for on-site test of substations.


  • The instrument can be used separately or linked to PC.
  • 320*240 LCD screen, thermal printer, interactive keyboard operation, and intelligent operation system.
  • Power electronics controlling technique has been adopted to output high current, which is high speed, high precision and continuous adjustability.
  • Current range can be automatically switched by multiple high precision sensors. 14 digit AD acquisition chip of high capacity.
  • Automatic data storage. Be capable of saving 200 testing results, which will not lose in power failure.
  • Optional for ampere-second characteristic test or through current characteristic test.
  • When linking to PC, it is available to do following operations, such as controlling the instrument, data importing, data saving, data report and data graph generation.
  • Protection functions for overheat, over-current and over voltage. Anti-interferencecapacity and good EMC(electromagnetic compatibility).
