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.

  • 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:
