M-PRO is a numerical multifunction motor protection relay having exhaustive protection functions and advanced communication capabilities. It provides complete protection, with current and voltage inputs for induction motor applications. This product includes metering, communications, fault logs, disturbance recordings and sequence of events with 1 ms timestamp resolution for analysis.

Draw out design, easy mounting and user-friendly settings simplify commissioning and make maintenance easy, saving time for end users.

M-PRO can be integrated using serial (IEC 60870-5-103, Modbus RTU/ASCII, DNP3) or Ethernet-based communication (IEC 61850, DNP3) via selectable electrical or fiber ports. It also comes with optional PRP (IEC 62439-3) support as an ordering option.

Protection Functions

  • Thermal overload, short circuit, earth fault, unbalance current, stall/ locked rotor and number of start protection
  • Loss of load, broken conductor, inrush current and breaker failure protection
  • Primary and back-up current and voltage protection
  • Runtime hours, start counter, start time, time to start and trip counter alarm

Features and Benefits

  • IEC, ANSI and user-defined IDMTL curves for all time grading and protection co-ordination
  • Complete user configurability of output contacts, status inputs and status LED indications on front panel
  • Second harmonic inrush blocking and restraint
  • Two stages of instantaneous/definite/inverse time O/C setting
  • Definite time/ANSI decay characteristics for function reset provides protection for pecking/flashing faults
  • 20 second long disturbance recording capability to capture high inertia motor starting characteristics

Flexible Communications

  • Serial and Ethernet interfaces with IEC60870-5-103, MODBUS, IEC 61850 communication protocols
  • Optional Parallel Redundancy Protocol (PRP), IEC 62439-3

Easy to Use and Maintain

  • Draw out construction
  • Site selectable 1A/5A CT rating
  • HMI with navigation and configuration keys and alpha numeric display
  • Intuitive Windows-based configuration and analysis software
