Fanox P44 Motor Pump Motor Protection Relay

Fanox offers advanced protection solutions for three-phase pumps, focusing on undercurrent protection to safeguard against conditions such as dry running without the need for external level sensors. These protection panels are ideal for submersible and surface pumps where running without load can cause significant damage. Here are the key features and benefits of Fanox three-phase pump protection panels:

Key Features:

1. Underload Protection by Undercurrent:

   • Dry Running Prevention: Detects undercurrent conditions indicative of running without load, such as a dry well, and automatically stops the pump to prevent damage.

2. Overload Protection:

   • Overcurrent Monitoring: Protects the pump motor from damage due to excessive current draw, ensuring safe operation under varying load conditions.

3. Phase Imbalance or Phase Loss Protection:

   • Balanced Operation: Detects phase imbalances or phase losses, which can lead to motor damage, and shuts down the pump to prevent harm.

4. Phase Sequence Protection:

   • Correct Phase Order: Ensures the correct phase sequence to prevent reverse rotation of the motor, which can cause mechanical damage.

5. Thermal Memory:

   • Motor Heating and Cooling Cycle Monitoring: Accurately tracks the thermal state of the motor, reproducing its thermal image to prevent overheating and ensure optimal performance.

6. Visual Indication of Tripping Cause:

   • Diagnostics: Provides clear visual indicators for trip causes such as overload, undercurrent, phase imbalance, phase loss, and phase sequence errors, facilitating easy troubleshooting.

7. Manual, Remote, and Automatic Reset:

   • Flexible Reset Options: Offers manual, remote, and automatic reset options to suit different operational needs and preferences.
