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 Antipumping relay:
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 • 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: Separate Mail
