RCM 202-AB RCM Residual Current Monitoring

RCM 202-AB Residual Current Monitoring device from Janitza enables continuous monitoring of residual currents in grounded TN systems according to DIN EN 62020/VDE 0663/IEC 62020.

Continuous monitoring can detect residual currents at an early stage and prevent system damage, including production downtime. The decisive factor here is to detect the usually creeping increases in residual currents before fuses trip residual current circuit breakers or data transmission/production is disrupted.
