Why do you need S0 contact? Can we not use the S0 contact in series with the 94 coil?

[@relayprotectionelectrical]

S0 contact is the CB aux contact. Purpose of Antipumping relay is to avoid another pulse to CC of CB. That means if CB is on then only function of Antipumping Relay comes. That's is why S0 contact is used in series with 94 R.

[@user-khanaamir8765]

If S0 NO contact is sufficient then why is 94 R NO contact used

[@rjshtk]

@@user-khanaamir8765 the NO contact of 94 is to prevent closing pulse from reaching a close coil in the event of cloding the cb on to a fault and holding the tnc lever for a while..
