• 6mA DC sensor, type A RCD sufficient
  • AC/DC sensitive residual current measurement
  • Fault current monitoring with external residual current transformer
  • Integrated fault memory (adjustable)

The AC/DC sensitive residual current monitoring module RCMB42… is used for residual current monitoring of AC charging stations for electric vehicles where direct or alternating fault currents are likely to occur, the value of which is constantly greater than zero.
