PC&S - Contactors

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.

(Table No.2)
