Residual current monitoring devices 5SV8. Residual current monitoring devices (RCMs) perform a variety of functions in protecting people and machines: they enable the detection of system faults and facilitate troubleshooting before the protective device shuts down, thereby increasing plant and operational safety while also saving costs. These residual current monitoring devices monitor an electrical system for the presence of an asymmetric residual current and indicate when it exceeds a certain level. Optionally, they can be used for alarm signaling and to trigger switching devices.
