Ready to use configuration

Build your SEPAM configuration :

–Choose the base unit e.g. :

Then add–connectors :

–Application :

–Working language :

–Manuals :



Current sensor inputs

CCA630 connector

The CCA630 connector is used to connect 3 phase current transformers to Sepam

contain interposing ring CTs with through primaries

Can be disconnected with the power on since disconnection does not open the CT secondary circuit.



Current sensor inputs

CCA634 connector

The CCA634 adds an input for a residual current transformer :

do not connect a core balance ct

do not use base’s Io input

contain interposing ring CTs with through primaries

can be disconnected with the power on since disconnection does not open the CT secondary circuit.
