Main Protection
- Overload Protection for motors
 Detection of motor overload current: If the motor draws excessive current due to heavy loads, obstructions, or other abnormalities, the relay will trip the circuit to prevent the motor from burning out.
- Phase Loss Protection for motors
  The relay detects and trips the circuit if a phase failure occurs in any phase of the power supply
