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.
