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
