RCM residual current monitors monitor electrical installations for residual currents resp. fault currents, display the current measured value and signal when a preset Response value is exceeded.
They can be used either for signalling or for switching. The devices are primarily used in applications where,depending on the load structure, switching off would be undesirable or problematic.
Significant cost reductions as a result of higher availability and minimal maintenance costs
Higher degree of fire and property protection
Universal versions for monitoring AC currents as well as pulsating and smooth DC fault currents
True r.m.s. value measurement (TRMS), therefore unrelated to waveform
