RCMA, RCMB series: Residual current monitors type B in accordance with IEC 60755 for monitoring AC currents, pulsating and smooth DC fault currents (0…2000 Hz). RCMS series: Multi-channel residual current monitoring system type A and B in accordance with IEC 60755 for monitoring AC currents, pulsating and smooth DC fault currents (0 (42)…2000 Hz).
