Anti pumping relay

Anti pumping Relay


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

Antipumping relay:

What s new

What’s new?

  • Replacement of Electromechanical antipumping relay by Electronic version due to obsolete component.

  • Capable of handling multi-voltages, from 24V to 380V

  • Input: DC/AC, Output: DC only. Associated closing release coil YF to have DC ratings only

  • New Electrical diagram: Change in assembling closing coil with relay

    Please see attached file for the updated diagrams.

Change in the offer structure

Change in the offer structure

  • Configured full product:

    • No impact in Elonet configuration.

    • Additional bridge options of internal electrical connection is not possible anymore. Only standard bridge remains unchanged.

    • Additional leaflet with new electrical diagram is attached with user manual systematically

  • Spare part:

    • Ref MV261200 will be replacing old references for RI mechanism in SF, LF, Evolis 24 and Evolis HP ranges

    • Ref MV261202 will be replacing old references for GmH mechanism in SF MCset4, SF F400 and SF2 fixed versions.

    • It is recommended to replace the closing coil and relay at the same time.

  • Level C adaptation:
