Product Details

• Phase Monitor Relays (3-phase monitors) provide cost-effective protection against premature equipment failure caused by voltage faults on 3-phase systems
• The SLU series multi-mode phase monitoring relay was designed for the convenience of plant operators, electricians 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
• NOTE Not recommended for generator or variable frequency drives
