DIGITAL MOTOR PROTECTION RELAY

MOTOR PROTECTION RELAY FOR SUBMERSIBLE PUMP STARTER CONTROL PANELS

The Motor Protection Relay is an advanced device engineered to safeguard submersible pumps in starter control panels. It measures critical electrical parameters and offers versatile, reliable protection against pump failures caused by various electrical and mechanical faults.

KEY FEATURES

  • Supply Voltage Monitoring: Continuously monitors input voltage to prevent
    damage from over-voltage and under-voltage conditions.
  • Current Measurement: Real-time tracking of motor current consumption helps identify overload and abnormal conditions.
  • Configurable Protection Levels: Allows users to set customised protection thresholds based on the pump’s capacity, ensuring compatibility across a wide range of motor ratings
  • Dry Run Protection Using Power Factor: Detects dry-running conditions by monitoring power factor, providing more accurate protection compared to conventional current-based systems.
  • Overload Protection Using Power Factor: Monitors power factor to identify overload conditions, delivering precise protection without relying solely on current measurements.
  • Short Circuit Protection: Rapid detection and isolation of short circuits to safeguard the pump and panel from severe damage.
  • User-Friendly Interface: Clear display of voltage, current, power, and power factor readings for simplified monitoring and diagnostics.
  • Rugged and Reliable Design: Built to withstand harsh environments, ensuring consistent performance even in challenging operating conditions.
  • Compact and Easy Installation: Fits seamlessly into any control panel design
