ELECTRICAL CHARACTERISTICS

The table below gives the general performances and ratings of the contactors, with reference to the requirements of International Standards IEC 947-4-1. The A.C. breaking capacity given is the R.M.S. value of the symmetrical component of the current and the making capacity given is the peak value of the total asymmetrical current.
