CCA634 Connector for 1A/5A + Ir CT Current Sensor Installation Sheet, Instruction Bulletin (ANSI), 63230-216-249A1, May 2007

A current transformer (1A or 5A) is attached to the rear panel of a Sepam relay via the CCA634 connector. The CCA634 connector can connect three (3) phase current transformers and one (1) zero sequence current transformer to a Sepam relay.
The CCA634 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.

The connector can be disconnected while powered on since disconnection does not open the CT secondary circuit.
