Monitoring relay RELPOL

- Voltage monitoring in 3-phase mains - monitoring of phase sequence ,phase failure, asymmetry;
- Voltage monitoring in 3-phase and 1-phase mains - multifunctions monitoring relays;
- AC/DC voltage monitoring in 1-phase mains - minimum value supervision with the histeresis mode;
- AC current monitoring in 1-phase mains - histeresis mode and the possibility of setting the tripping delay;
- Current monitoring in 3-phase mains - timing adjustment for start-up suppression time and tripping delay;
- Monitoring of motor temperature - relay responds to short circuit or wire break;
- Level monitoring of conductive liquids MIN, MAX.
