Advanced Current-Based Numeric Relay - mPRO-100

FEATURES
  • Overload, Short Circuit, Under Current, Unbalance, Phase Loss, Phase Reversal, Stall, Locked Rotor, Earth Fault (Residual/CBCT), Three Phase RMS current, Thermal content (%), Unbalance current (%)
  • Three Phase RMS current, Thermal content (%), Unbalance current (%)
  • One Fault/Failure record to identify the last failure
  • In-built real-time clock available. Fault gets registered with date and time to identify the time/date of failure.
  • Accumulation of motor operating time to analyse motor service factors like bearing check, refuelling cycling etc.
  • In-built fail-safe operation feature available for trip contact
  • Programmable Automatic/Manual reset functions available for different schemes.
  • Thermal overload protection with different trip classes
  • All parameter settings are protected via password protection to avoid unauthorised access
The mPRO-100 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-100 offers the following features in a compact, modular & smart 35 mm DIN-rail mounting enclosure.

The C&S mPRO-100 relay provides comprehensive motor protection by monitoring current and other parameters to guard against issues like Overload, Short Circuit, Under Current, Unbalance, Phase Loss, Phase Reversal, Stall, Locked Rotor, Earth Fault and operating conditions, and diagnostic capabilities such as fault recording and communication via MODBUS RS-485 or an analogue output.
