- RCM1000V RCM100V monitors residual currents in grounded power supply systems. Used as a current relay it monitors AC- or pulsing DCcurrents for exceeding upper or lower limits. Insulation faults can be caused by damages (mechanical, thermic or chemical) of insulations or also by humidity or pollution. At currents > app. 250 mA (at 230 V) at a location, the fault can lead to danger of fire.
- Particularly useful in monitoring in systems in which no fault current circuit breaker can or shall be used, because an immediate switching would have wideranging consequences, such as breakdown of computersystems or interruption of processes of sensitive goods. RCM1000V do NOT replace fault current circuit breakers for protection from electric shock but they can complement it by detection an fault in the insulation before the systems has to be shut off.
