This monitoring relay is used in three-phase networks for monitoring the phase sequence and phase failure and can monitor the temperature of motors with built-in PTC sensor.
For phase monitoring and temperature monitoring, one relay output is available with a normally open contact.
Optionally, an error memory can be used that holds messages up to a reset.
The wide-voltage power supply enables a universal use.
The cable is connected via screw terminals.
