The RCM 201-ROGO enables continuous monitoring for residual currents in TN-S systems and complies with the DIN EN 62020/VDE 0663/IEC 62020 standard. This refers to residual current monitoring devices which check circuits for the occurrence of a residual current and trigger an alarm if a limit value is exceeded.

The RCM 201-ROGO records residual currents according to type A and can be connected to the RCM inputs of Janitza network analyzers or read out directly via Modbus. The currents are recorded with Rogowski coils. The RCM 201-ROGO can be used wherever conventional residual current transformer cannot be installed mechanically, e.g. with large cross-sections, busbar systems or for retrofitting in existing systems where space is limited.
