CCT640 Connector for VT Voltage Sensor Installation Sheet, Instruction Bulletin (ANSI), 63230-216-250A1, May 2007

Published date: 19 May 2020

Issue
Sepam relays can connect to any standard voltage transformer (VT) with a rated secondary voltage of 100240 V. Square D offers a wide range of voltage transformers:
to measure phase-to-neutral voltages: VT with 1 insulated MV terminal
to measure phase-to-phase voltages: VT with 2 insulated MV terminals
with or without integrated protection fuses
The CCT640 connects the four additional voltages available in Sepam B83. It provides impedance matching and isolation between the voltage transformers and the input circuits of the Sepam relay. The connection port (B2) is not visible in Figure 1, behind the CCT640.
