    E3 Plus with Voltage Protection & Energy Monitoring
  • 4. Current Protection
    • The E3 Plus with Voltage Protection and Energy Monitoring helps protect your electric motor investment by preventing damage from the following events:
      • Thermal Overload
      • Phase Loss
      • Jam Warning
      • Stall
      • Under Load
      • Current Unbalance
      • Ground Fault Current
      • Ground Fault Current Filtering for High Resistance Ground Systems
  • 5. Thermal Overload
    • The E3 Plus Model EC5 helps protect your electric motor from consuming more electric current than its nameplate rating which can be caused by:
      • Excessive load
      • Incorrectly sized motor
      • Low incoming voltage
      • Damaged equipment
    • The trip class of the motor is selectable between 5 and 30
      • Trip class represents the maximum trip time in seconds when the motor consumes 720% of the Full Load Amperes (FLA) rating of the electric motor
    • %Thermal Capacity Utilization (%TCU) can be monitored to continuously view the thermal status of the electric motor
  • 6. Phase Loss
    • The E3 Plus Model EC5 helps protect your electric motor when one phase of power is lost causing the remaining phases to consume more electric current
    • Phase loss is typically caused by:
      • Blown fuse
      • Loose wire
      • Damaged contactor contacts
    Phase loss is a leading cause of motor failure!
  • 7. Jam, Stall, & Underload
    • The E3 Plus Model EC5 helps provide these protection functions to ensure the safe operation of your electric motor or machine:
      • Jam protection
        • Prevents an electric motor from running when a sudden rise in electrical current consumption occurs during its normal running operation
      • Stall protection
        • Prevents an electric motor from running when an extended amount of electrical current is consumed during its starting sequence
      • Underload protection
        • Disables an electric motor when a sudden drop in electrical current occurs indicating a possible mechanical malfunction
  • 8. Current Imbalance
    • The E3 Plus Model EC5 can help protect against the unequal consumption of electrical current on each of the three phases for your electric motor
    • Current imbalance protection can be used to prevent electric motor damage from:
      • Imbalance in the voltage supply
      • Unequal motor winding impedance
      • Long and varying cable lengths
  • 9. Ground Fault
    • The E3 Plus Model EC5 has the capability to monitor for short circuits or current leakage to ground and provide equipment level protection (20mA 5A)
    • Low levels of ground fault current can rise very quickly causing damage to the electric motor if not caught early
    • The E3 Plus Model EC5 can monitor ground fault current for:
      • Solidly grounded systems
      • High resistance grounded systems
    • Ground Fault Current Filtering option for High Resistance Ground Systems to prevent nuisance trips
    It is important to catch ground faults at the leakage stage!
