Siemens 3UG Phase & Voltage Monitoring Relay | Phase Sequence / Failure

The Siemens 3UG monitoring relay protects motors, pumps, elevators and compressors by tripping the contactor when it detects wrong phase sequence, loss of a phase, phase imbalance or abnormal voltage – common causes of motor burn-out on unstable networks.

Key features

• Detects phase sequence errors and phase loss
• Over/under-voltage monitoring (model dependent)
• Changeover output contact
• LED status indication, DIN-rail housing
