A current transformer (1A or 5A) is attached to the rear panel of a Sepam relay via the the CCA630 connector. The CCA630 connector can
connect three current transformers to a Sepam relay.
The CCA630 connector contains interposing ring current transformers (CT) with through primaries. When measuring phase and zero sequence currents, these primaries provide impedance matching and isolation between the 1A or 5A circuits and the Sepam relay.
