Answer / mm
the anti pumping device is used to avoid continously
energising the breaker closing coil once the CB has already
closed. this is done to avoid burning the coil

The anti-pumping relay allows the breaker to close only
once for each press of the 'close' pushbutton (or rotation
of the handle).

Answer / k.ramesh,vepl
This Coil is used to avoid the continuous supply of the
breaker coil during faulty condition,once we are giving the
closing pulse during uncleared faults condition the breaker
will close one time only. After we are giving many more
closing pulse to the breaker,cannot perform that closing
operation with the help of anti pumping coil.

Anti pumping relay is used to prevent closing coil from
being burnt by the repeated closing command. Closing coil
is not designed for continuous electrical operation and
once the closing coil is energised, breaker will get on and
it will be remain energised mechanically until any trip
command is available. So continuous supply is not required
for closing coil.

Answer / ahmed arafa _bapetco
Anti-pumping relay is used to avoid closing of the circuit
breaker when there is afaulty case , so the closing coil of
the circuit breaker can not be energised until the path is
healthy and the trip is not exist

Answer / lokesh thota
Pumping means if breaker is close & give close command (electrical or manual) to it,spring will discharge & charge again. To prevent this pumping anti pumping feature is required,which in turn will help to restrict unnecessary operations of breaker mechanisms.

The function of Anti Pumping relay is to cut off the supply to CB closing coil in case of TNC switch spring failure and prevent CB hunting effect i.e. continuous closing, opening operation.

A device, which function to trip a circuit breaker, contactor or equipment or to permit immediate trip by other device or to prevent immediate re-closure of a circuit interrupter in case it should open automatically even through its closing circuit is maintained in closed condition.
