HRN-56/208V is a voltage monitoring relay for 3-phase networks that checks phase sequence, phase failure and undervoltage, e.g. for correct motor connection.
Key features
- Supply = monitored voltage: 3× 208 V L-L (3× 120 V L-N), 50-60 Hz
- Adjustable lower level Umin 70 – 95 % Un; below 60 % Un the output opens immediately
- Monitors phase sequence and phase failure
- Adjustable time delay t2 0 – 10 s
- Output: 1× changeover 8 A/AC1
- DIN rail housing, 1-module, 90 × 17.6 × 64 mm
