SLU-100 Series Universal Phase Monitor

Phase Monitor Relays 3-Phase Monitors provide cost-effective protection against premature equipment failure caused by voltage faults on 3-Phase systems Wye or Delta. The SLU Series multi-mode phase monitoring relay, was designed for the convenience of electrician's, maintenance managers and engineers. A single SLU Phase Monitoring Relay can be easily adjusted for the voltage, imbalance percentage and time delay requirements to protect against unbalanced voltages or single phasing regardless of any regenerative voltages.Both DELTA and WYE systems may be monitored. In Wye systems, connections to neutral are NOT required. The SLU-100 Series is UL Listed under UL File Number E55826.
