24–600 Vac devices are rated for 50/60 Hz.
Peak inrush current is present for 2–6 ms after
activation. This number is provided so that fuses and
supplies can be chosen appropriately.
Ratings for 480 Vac and 600 Vac devices are at the
input of the upstream transformer, included with the
accessory and specified in GEH6520, which powers the
device. For voltage and current ratings at the switch
terminal block, see SPUV120AC.

Ratings for 480 Vac and 600 Vac devices are at the input of
the upstream transformer, included with the accessory and
specified in GEH6519, which powers the device. For voltage
and current ratings at the switch terminal block, see
SPSTL120.

Figure 17. Undervoltage Release module.
The catalog numbers for the UVR for various voltage
applications are listed in Table 13. For installation
instructions see GEH6285 or GEH6520.
Operation
Apply control voltage to terminals 29 and 30 of the terminal
strip on the right side of the switch. When the applied
control voltage is above 80% of the UVR’s rated value, the
switch can be closed. When the voltage drops to 35–60% of
the rated value, the UVR will open the switch.

Table 12. Catalog numbers and voltages for the Shunt Trip with Lockout.
Operation
Apply control voltages to terminals 31 and 32 of the terminal
strip on the right side of the switch to open the switch. The
Shunt Trip with Lockout will cause the switch to open when
the control voltage is greater than 75% of the dc-rated value
or 55% of the ac-rated value.
3-7 Undervoltage Release
The Undervoltage Release (UVR) module, shown in Figure
17, opens the switch when the input control voltage drops to
35–60% of its rated value and prevents an open switch
from closing until the input control voltage is greater than
80% of the rated value.
If the switch is equipped with a EnteilliGuard® Control
Unit, it is configured so that only ground fault trips will
activate a bell alarm alarm only or bell alarm with lockout
