RNPP-311M 3 Phase Voltage Monitoring Relay 5A 220V

Description

The RNPP-311M voltage monitoring relay is designed for protection of three-phase loads against major types of mains faults, as:

• RMS voltage reaching beyond admissible thresholds;
• phase sequence order violation and phase coincidence;
• violation of the mains voltage phase completeness and symmetry.

The device performs monitoring of the main circuit parameters and de-energizes load when the parameters fall beyond specified boundaries. The front panel LEDs display the following:

• presence of voltage in the mains;
• load status (ON/OFF);
• type of fault.
