Motor Protection Relay
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.
Key Features & Capabilities
Thermal overload protection with accurate motor thermal modeling
Locked rotor (stall) and excessive start time protection
Phase loss, voltage unbalance, and phase reversal detection
Earth fault and ground protection for motor winding safety
Negative sequence current protection for unbalanced supply conditions
Undercurrent/underpower protection for detecting mechanical failures (e.g., pump cavitation)
Start supervision including number-of-starts limiting to prevent overheating
Fault log and disturbance recording with communications for SCADA integration
IDEAL FOR Industrial facilities in manufacturing, mining, water utilities, oil & gas, and any environment where large electric motors are mission-critical and motor downtime directly impacts operations or safety.
