Schneider Electric PMR-440N7 Phase Monitoring Relay
Schneider Electric PMR-440N7 Phase Monitoring Relay
Product Description :
- It is an electrical protection device used to monitor the voltage and phase conditions in a three-phase power system.The relay is connected to all three phases: L1, L2, and L3.Some models may also connect to neutral (N) if required.It continuously monitors the voltage and phase relationships.
- The relay reads the voltage level of each phase.The relay determines the rotation direction of the three phases (e.g., L1 → L2 → L3).If the phase sequence is incorrect, the relay trips, preventing motors from running in reverse.
