How do a select a D65 relay?

The D65 Monitoring Relays can be found in Volume 5 Tab 5 of Eaton's Catalogs. 

D65VMC monitoring relays are used to protect against phase reversal but are no longer offered (replace with D65VMLP). 

 
D65PLR monitoring relays are used to protect against phase loss and phase reversal.
 
D65PAR monitoring relays are used to protect against phase loss, phase reversal, and undervoltage but are no longer offered (replace with D65VMLP).
 
D65VML monitoring relays are used to protect against phase loss, phase reversal, phase imbalance, and under/overvoltage.
 

Over/Undervoltage Relays (Fixed Time Delay) provide protection to equipment where either an over- or undercurrent condition is potentially damaging.  The dropout time delay on undervoltage is fixed at 500ms.

 
Over/Undervoltage Relays (Adjustable Time Delay) provide protection to equipment where either an over- or undercurrent condition is potentially damaging.  The dropout time delay on undervoltage is adjustable from .5 to 10 seconds.
 
Voltage Band Relays provide protection to equipment that is required to operate within an upper and lower voltage limit.
