    GDAS-500 DC Circuit Breaker Test Set hits:

    Product Description

    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, also for DC fuse at 6-500A. 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-interference capacity and good EMC (electromagnetic compatibility). 


    •  Power supply: AC220V±10%, 50Hz±0.5Hz
    • Testing current range: 0-500A (can be extended to 1000A)
    • Testing current ripple coefficient: <2%
    • Stability of output current: ≤0.5%
    • Ampere-second characteristic test: Time: 0-9.9s; Time resolution(min.): 0.1ms
    • Through current characteristic test: time: 0-9999s; Time resolution(min.): 0.1s
