The mPRO-90 protective relay is an advanced current-based numeric relay that provides multi-protection and monitoring.
The relay offers reliable protection for LV and MV motors, which are either operated via power contactors or power circuit breakers.
The C&S mPRO-90 relay provides comprehensive motor protection by monitoring current and other parameters to guard against issues like overload, undercurrent, Earth Fault, Phase loss, Phase reversal etc. Its key features include protection from thermal overload, protection during start-up (locking of the rotor) and operating conditions, and diagnostic capabilities such as fault recording and communication via MODBUS RS-485 or an analogue output.
