Description

The EMR4 / EMR5 series will be fully replaced by the end of June 2019. Applications: Current monitors for universal use Phase monitors for monitoring destruction/damage protection for individual system sections Phase sequence relays monitoring the rotating field Unbalance relays for reliable phase loss detection Multifunctional three-phase monitors Asymmetric phase monitoring relays in a single device Level monitoring relays for monitoring fill levels Earth leakage monitors for enhanced operational safety Versions: Phase monitor EMR5-W The phase monitor EMR54-W in addition to the monitoring the rotary field, also monitors the level of the applied voltage – i.e. monitoring destruction or damage protection of individual system sections. Features: Phase sequence detection Phase failure detection Status display via LED The relay features a second changeover contact that is used for indication purposes Two versions for the monitoring voltage U = 160–300 V AC, 300 V–500 V AC and 350 V–580 V AC Selectable response and off delay (0.1 s – 10 s) Earth leakage monitor EMR4-R The main area of application of the earth leakage monitor EMR4-R is the monitoring of auxiliary circuits for an earth fault to increase operating safety.
