EMR‑3MP0 Motor Protection Relay
The EMR-3MP0 motor protection relay is a multifunctional microprocessor-based
protective relay for the protection of any size motor at all voltage levels. It is most
commonly applied on medium voltage or larger motors. The EMR-3MP0 relay is a current
device with built-in protection that provides complete and reliable motor protection,
monitoring, diagnostics, metering, and starting control functions.
The range of protection functions makes the EMR-3MP0 relay the perfect successor device
of the MP‑3000 motor protection relay.
The intuitive operating concept with plausibility checks and extensive commissioning
functions such as the built-in fault simulator allows a safe and time-optimized
maintenance and commissioning. The parameter setting and evaluation software
PowerPort-E can be used consistently across the entire family of devices.
