CBCT with SPAJ 140C relay

05/10/2008 6:50 AM

Hello Friends,

Here we have SPAJ 140C O/C & E/F relay in our system.

We want to connect CBCT of 50/5 A ratio, with POC (Primary operating current) – 5A, POB (Primary out of balance)- < 5A, setting -50mA.

Can we use above CBCT with SPAJ 140C relay for Earth fault? or we need to install CTUM type sensitive earth fault relay.

Regards,

Sudhir
