• Additional SPNO contact for signaling secondary systems
• Protects against phase loss, phase reversal, phase unbalance, undervoltage, overvoltage & rapid cycling
• True RMS voltage measurement ensures accurate sensing across more applications
• Retains fault indication and continues monitoring all voltages even with a lost phase
• Full fault indication on top of unit for easy troubleshooting
• Manual reset option works with external switch to reset the relay from outside the enclosure
• 5A SPDT + 5A SPNO contacts
