  • Page 3: General Description

    660 Volts is the maximum system operating voltage for the D64RPB125 when passing the system power conductors through the built-in CTs. The CTs are positioned within the relays so that they line up with the terminals on the associated Eaton’s Cutler- Hammer E125 (15 –...
  • Page 4 PUB IB04300001E D64RPB125 DIGITAL GROUND FAULT RELAY Three seconds after the ground fault current drops below the trip current set point the relay will reset and the red TRIP LED is turned off. If the control voltage is removed by the trip action of the output relay (i.e. it operates the shunt trip of the breaker that is providing the control voltage), the relay will reset with a short delay and the red TRIP LED is turned off.

  • Page 5: Dipswitch Settings

    PUB IB04300001E D64RPB125 DIGITAL GROUND FAULT RELAY If control voltage is removed from terminals N- & L+ while a ground fault is detected, the output relay resets and the red TRIP LED turns off. If the ground fault has not been cleared when control voltage is restored, after 500 milliseconds the relay will trip and the red TRIP LED will resume flashing, regardless of the time delay set on the Trip Delay DIPswitch.

  • Page 7: Output Relay Contact State

    PUB IB04300001E D64RPB125 DIGITAL GROUND FAULT RELAY As indicated in the General Description, it is recommended that the ground fault TRIP LEVEL setting be kept as close to the charging current as possible. This will provide maximum safety for operating personnel and equipment protection. On resistance grounded systems, the TRIP LEVEL setting should be set lower than 20% of the Neutral Grounding Resistor let-through current.

    The terminals are pull apart. A screw mounted locking block is located at each end of the 8 point terminal block for maximum security. An RJ-12 port is provided for connection of a D64DMCC display suitable for mounting in the Eaton’s Cutler-Hammer MCC door mounted panel. See section 4.
