The RCM 202-AB enables continuous monitoring of TN-S systems and complies with DIN EN 62020/VDE 0663/IEC 62020. This refers to residual current monitoring devices which check circuits for the occurrence of a residual current and trigger an alarm if a set alarm value is exceeded. The two-channel residual current monitoring device is suitable for the monitoring of residual currents type A to Type B+.
For standard compliant type A measurement on DIN rails the Janitza RCM 201-ROGO can be used.
