anti pumping relay

[@satya7077]

86A & 86B NC contact used in series in closing ckt. During electrical fault, 86 A & 86 B doesn't allow the CB to close. Antipumping is used in case of TNC stuck & Mechanical problem in CB.

How antipumping relay will peak after once we give close command from tnc and realise the tnc

[@dustymanning7378]

How does the 94 relay drop out after the fault condition has cleared so that you can close the breaker?

[@MrOptimusPrime.]

94 relay will drop out, once TNC switch is back to N (Neutral) position according to this circuit. There will be no coil supply.
