M401

Electronic Current Burden (5A)

Electronic Current Burden M401 is used as a load in the secondary circuits of Current Transformers with secondary current 5 A during their verification and calibration

    FEATURES AND BENEFITS

    • Rated current – 5 A
    • Rated power range:
      0,5 to 50 V·A, cosφ = 0,8 at 50 Hz
      0; 0,5 to 50 V·A, cosφ = 1 at 50 Hz
    • Cable, contact and internal test set (Comparator) resistances are compensated by four-conductor connection
    • Non-breaking measuring circuit during switching of the burden
    • Possibility of using with automated CT calibration systems
    • Small size and low weight

    APPLICATIONS

    M401 is used by:

    • Manufacturers of Current Transformers
    • On-site testing of Current Transformers
    • Calibration Laboratories
    • Metrology Institutes
