Digit 10 – Under Voltage Release (UVR)
UVR with Fixed Time Delay *
48Vac/dc
60-72Vdc
110/130Vdc; 120Vac
Blank/none
*The UVR Shunt Trip with Fixed Time Delay is specifically intended for
applications where a delay period ('ride- through') is required due to
potential voltage events. The design delays are 50msec when system
voltage drops to 50% and 20 msec when system voltage drops below
50%.
• An optional External UVR Time Delay Module is available in a 1 - 3sec
delay.

Digit 11 – 2nd Shunt Trip or UVR
2nd UVR with Fixed
Time Delay **
2nd Extended
Range Shunt Trip
(ANSI/UL)*
*The Extended Range Shunt Trip is specifically intended and required for UL
ANSI Ground Fault applications. The pick up range is 55-110% of the ST coil
voltage.
**The UVR with Fixed Time Delay is specifically intended for applications
where a delay period ('ride- through') is required due to potential voltage
events. The design delays are 50msec when system voltage drops to 50%
and 20msec when system voltage drops below 50%.
• An optional External UVR Time Delay Module is available in a 1 - 3sec
