Description Of Function When the proper 3-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized after the Restart Delay is completed. Any one of five fault conditions will de-energize the relay after a delay. As standard, re-energization is automatic upon correction of the fault condition. A multi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting (see right). Product Overview Features Protects against phase loss, phase reversal, phase unbalance, undervoltage, overvoltage & rapid cycling Universal voltage range of 190-500V—greater range that covers more global applications 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 5A SPDT/SPNO output provides isolated contact for alarm circuits | Learn More Enclosure Style Plug-in case utilizing industry-standard 8 pin octal sockets Configuration / Contact Rating SPDT/SPNO 5A @ 277V AC / 5A @ 30V DC;1/3HP @ 120/240V AC, B300 Pilot Duty Application Information Load (Burden): Less than 40 VA Minimum/Maximum Voltage: 156-550V, all 50/60Hz. +5#% Reset: Automatic upon correction of fault. Output Contacts: 5A @ 277V AC / 30V DC;1/3HP @ 120/240V AC; B300 Pilot Duty Life: Mechanical: 10,000,000 operations, Full Load: 100,000 operations Temperature: -28° to 65° C (-18° to 149° F) Operation When the proper three-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized after the Restart Delay is completed. Any one of five fault conditions will de-energize the relay. Re-energization of the relay is automatic upon correction of the fault condition. A bi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting. File Downloads DIGITAL CATALOG
