The mPRO-200 protective relay is an advanced current-based numeric relay that provides multi-protection and monitoring in a compact DIN-rail enclosure. The relay offers reliable protection for LV and MV motors, which are either operated via power contactors or power circuit breakers.
mPRO-200 comprises of DIN Rail mountable Base Module and a Panel mountable Display Module.
mPRO-200 offers the following features in a compact, modular & smart design.

The C&S mPRO-200 relay provides comprehensive motor protection by monitoring current and other parameters to guard against issues like overload, phase loss, and phase reversal. 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.
