VARIMETER RCM Residual current monitor IR 5882 Reliable detection of fault currents Our compact residual current monitor IR 5882 of the VARIMETER RCM family of DOLD measures AC fault currents and pulsating DC fault currents. The device signals them via its potential-free change over contacts dependent on the adjusted respond values for prealarm and alarm. The IR 5882 is also suitable for the use in consumer units and industrial panels due to the integrated residual current transformer and a depth of only 63 mm. Residual current monitors are measuring and monitoring residual- and fault currents in grounded voltage systems. They will be used in plants where they should signal a failure but not disconnect. Compared to current protection switches that are switching-off immediately at certain measuring fault currents, residual current monitors are showing a fault current early and are signaling an insulation degradation for an output contact for example. Due to the early detection of insulation faults as well as preventive maintenance and service outside the operating time, unexpected stand stills of machines and plants can be avoided and do not result to inadvertent operating interruptions, damages or high costs. Your advantages Integrated residual current transformer (diameter 28 mm) Time- and cost optimal service / maintenance Preventive fire- and plant protection by early fault signal Simple adjustment via snapping rotary switches Wire break detection in measuring circuit Wide auxiliary voltage range AC/DC24 - 230V
