Priority Innovation


Before tripping unexpectedly, the RCD displays the residual current level so that the actual tripping can be prevented. In addition, the SCHRACK PRIORI indicates excess residual current caused by lighting, power supply units, etc. to delay tripping and to prevent data loss or down-times.

These types of RCDs are independent of the mains voltage and can be used as additional RC protection measures if installed according to usage specifications.
