  • For MRCD applications in combination with a circuit breaker
  • AC/DC sensitive measured value acquisition type B
  • For personnel protection applications
  • Insensitive to load currents due to magnetic full-screen

The AC/DC sensitive residual current monitoring module RCMB35-30-… is used for residual current monitoring in earthed systems (TN and TT systems).

It detects direct and/or alternating fault currents. The switching output opens as soon as a response value of 30 mA is reached.

By the application of an RCMB35-30-01 and a switching component with isolating properties this device combination fulfils the requirements of DIN EN 60947-2 Annex M for an MRCD protective device. The switching component must not exceed a disconnection time of 20 ms.
