  • Description

  • LS-RCT-ABCF7A Type A/B/AC/F Residual Current Operated Circuit Breaker Tester is a fully automatic comprehensive leakage current performance testing device specially developed for electronic and electromagnetic residual current circuit breakers (RCD/RCBO). Adopting intelligent single-chip microcomputer control, it can conduct fully automatic operating characteristic tests on Type A, Type B, Type AC and Type F residual current protective devices in accordance with preset test procedures.

    LS-RCT-ABCF7A Type A/B/AC/F Residual Current Operated Circuit Breaker Tester supports the output of various residual current waveforms, including power frequency sine wave, pulsating DC, DC superposition, rectified waveform, high-frequency sine wave, smooth DC and composite wave. It features stepped adjustable output voltage, continuously adjustable test current, audible and visual alarm for unqualified items, simple operation, high testing efficiency and excellent stability. It is an ideal special testing equipment for batch rapid inspection on production lines and type tests in R&D laboratories of circuit breaker manufacturers.
