External AC Source contactor
When the maximum transfer current is greater than the rating of the SP PRO (63A or 63A per phase for
SPMC models and 125A or 125A per phase for the SPLC models) an external AC source contactor and AC
source current transformer (CT) may be fitted. With an external contactor, transfer currents of up to 250A
are possible (250A per phase in a three phase system).
The line diagrams below are for the external contactor in both a single phase configuration and three phase
configuration.
For more detailed information please see “TN0057_02 SP PRO External AC Source Contactor Option.doc”
available on the USB stick packed with the SP PROGO or from the selectronic web site:
