Protective Relays
Omicron PHR
The OMICRON-PHR is a self-powered phase monitoring relay designed to continuously monitor AC voltage and protect systems and equipment from phase-related faults. It is ideal for applications such as closed-loop control operations, conveyor systems, and motor protection against incorrect phase sequence, phase unbalance, and phase failure.
Special Features:
- True RMS voltage measurement for accurate monitoring
- Self-powered operation
- Automatic reset when fault conditions are cleared
- Compliance with IEC 61010-1:2010
- LED indications for phase unbalance, phase failure, and incorrect phase sequence
- Suitable for both 3PH 3W and 3PH 4W systems
