Evolution of Antipumping relay

Anti pumping Relay
Description:
The anti-pumping relay is built into the mechanism of circuit breakers to ensure that the opening order
has priority.
This function prohibits re-closing of CB in case of fault tripping. In other words it prevents the possibility of
maintaining a permanent closing order inorder to avoid « pumping » of the CB
