The RCMS system consists of one or several RCMS460-D/-L and RCMS490-D/-L residual current evaluators. In combination with the associated measuring current transformers, the evaluators are capable of detecting and evaluating fault, residual and operating currents in earthed power supply systems. The maximum voltage of the system being monitored is depending on the nominal insulation voltage of the applied measuring current transformers when busbar systems are used or of the nominal insualtion voltage of the cables or wires led through the transformers.
- Optional AC, pulsed DC or AC/DC sensitive measurement by selecting the respective measuring current transformer for each channel
- 12 measuring channels per single device
- Response ranges 10 mA…10 A (DC…2000 Hz) 6 mA…20 A (42…2000 Hz)
- Alarm history with date and time stamp for 300 data records
