This unit has been known as the D64RPY1 and D64RPY2 brand labelled for Eaton Corp. As of November 2023 we decided to sell this unit on this website as the DGF5.

The DGF5 is a microprocessor based ground fault unit for use on solidly grounded or resistance grounded systems. This digital electronic unit measures ground fault current using a built-in 28 mm zero sequence Current Sensor (CS).

The system will react to alternating current (AC) only and will reject direct current (DC) signals. Accuracy will be maintained over a frequency range of 45 - 450 Hz, making it suitable for variable frequency drive applications. The DGF5 is a Class A device as defined in the IEC 60755 standard; it is therefore fully characterized for operation with sinusoidal AC and pulsating DC currents. The maximum system operating voltage for the DGF5 is 660 V.

The DGF5 houses a non-isolated universal power supply of 24 – 48 V AC or DC and is equipped with form ‘C’ (3-wire), changeover contacts. The relay operating mode is Pulsed Trip/Auto Reset. The Ground Fault Current Trip level is factory set at 500 mA, the Trip Delay Time is factory set at 500 ms. By pressing the remote ‘TEST’ button, a functional test of the DGF5 is invoked, three seconds later the unit resets.

Seven coloured wires simplifies connection of field wiring. To ensure that the DGF5 will function in severe circumstances, it is encapsulated in polyurethane (PUR) to make sure it is not vulnerable to mechanical shock, vibration nor weather.
