The residual current monitor IR 5882 of the VARIMETER RCM series is used for early detection of insulation faults and detects residual currents with alternating currents and pulsating direct currents in earthed systems (type A). The residual current measurement is carried out via an integrated current transformer. In contrast to the residual current circuit breaker, the residual current monitor IR 5882 does not immediately switch off the mains when a fault is detected, but only indicates the fault. LEDs indicate operational readiness, pre-alarm and alarm. Other features include a check and delete function. The IR 5882 residual current monitor thus offers an information advantage for targeted and cost-effective maintenance measures before the system comes to a standstill.
