The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the breaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the close command is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.

What is operation of an antihunting relay in circuit breaker?
This is also called anti pumping relay. for understanding you have to understand the working of breaker. positive extends to "Low Pressure Lockout" & "Low Pressure Alarm". after maintain the pressure in breaker these NO becomes NC and when breaker closes the auxiliary of breaker get closed and simultaneously extend the positive to the antipumping relay coil by auxiliary contact. by this coil get energised and holding contact get connected and the one of the contact of antipumping coil (NC) become NO which disconnect the command supply of main breaker. by this till when the antipumping relay get energised no further command (+ve) extends to breaker closing coil. This is Antipumping/ Antihunting Relay.
