Eaton’s D65 series phase monitoring relays prevent motors from running at temperatures above approved ratings. The devices provide protection against phase loss, phase reversal, and phase unbalance due to blown fuses, broken wires or worn contacts. They monitor simultaneous voltage drops/increases and help to prevent damaged machinery and the injury of personnel.

EATON Digital Display Unit, LCD Display, 5 in L x 3-3/4 in W x 3-3/4 in H Dimensions

• Continuous reading of actual ground fault current, employing auto ranging
• Display of the pre-trip ground fault current, after a trip has occurred (flashing display)
• Display of the trip current setting, after a test trip has been activated
• Test and RESET pushbuttons
• The RESET button must be held pressed before the test is pressed to invoke the test procedure
• The function of this button can be enabled/disabled by inserting the interconnecting cable from the D64RPB100 relay into one of two sockets, TEST on or TEST off, on the right side of the display
• Pushing verify pushbutton shows if D64RPB100 tripped due to a ground fault prior to loss of its control voltage red trip LED lights or if there was no ground fault green run LED light strip-green run LED lights
• This indication will remain available for at least ten hours
• The numerical LCD window displays actual ground fault current in amps
• When a 5000:5 ratio interposing CT is used, all displayed values are to be interpreted as kA rather than amps
• Used with 30 ft of standard 4-wire telephone type cable connection
• Use with D64RPB100 Series B1 digital ground fault relay
