Operation
The Bell Alarm with Lockout prevents reclosing of the
switch after a ground fault trip until the reset button on
the front of the module is pressed. This trip can be caused
by a ground fault condition detected by the Control Unit.
In addition, the Bell Alarm with Lockout provides
normally open (NO) and normally closed (NC) alarm
outputs available at the terminal block on the right side of
the switch, as illustrated in Figure 14. These outputs are
returned to their normal state when the Bell Alarm with
Lockout reset button is firmly pressed.
Figure 14. Bell Alarm with Lockout connections on the right
terminal block. The contacts are shown in the reset state.
3-5 Shunt Trip
The Shunt Trip module, shown in Figure 15, allows the
switch to be tripped electrically from a remote location.
Figure 15. Shunt Trip module.
If the switch is equipped with a Power+™ Control Unit, it
is configured so that only ground fault trips will activate a
Bell Alarm–Alarm Only or Bell Alarm with Lockout.
The catalog numbers for the Shunt Trip for various
voltage applications are listed in Table 11. For installation
instructions see GEH–6284 or GEH–6519.

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 GEH–6519,
which powers the device. For voltage and current ratings at the switch
terminal block, see SPST120.

Operation
Apply control voltage to terminals 31 and 32 of the
terminal strip on the right side of the switch to open the
switch. The Shunt Trip 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.
