Testing Static Trip II
TM
Devices
1 2
Trip devices can be tested when mounted on a circuit
breaker in the disconnect position in its cubicle, with the
device on a circuit breaker removed from its cubicle or with
the device separate from the circuit breaker.
The following instructions cover testing of all the elements for
the most complicated type of trip device. Other types do not
contain all these elements. See the listing and description of
available types in Table 2.
Types Available
Tl(OT) Long Time and Instantaneous
TS(OT): Long Time and Short Time
TSI(OT): Long Time, Short Time and Instantaneous
Tl(2T): Long Time and Instantaneous
TS(2T): Long Time and Short Time
TSI(2T): Long Time, Short Time and Instantaneous
TIG(3T): Same as T(2T), plus Ground Fault
TSG(3T) Same as TS(2T), plus Ground Fault
TSIG(3T) Same as TSI(2T), plus Ground Fault
Devices with (OT) designation do not include targets.
Devices with (2T) designation include targets to indicate
overload trip and short circuit trip, while those with (3T)
designation also include a ground trip target.

*Exceeds maximum continuous current rating of frame--do not use these settings.
** Breaker may not trip with this ground fault setting.
*** Long time element continually adjustable from A through G.
General Notes
1.
The TRIPPING XFMR RATING values represent the
primary value of the current transformer ratio in am-
peres. The secondary value is one ampere.
2.
The pick-up settings of the long time element are
continuously adjustable and are calibrated at points “A”
through “G” as shown in the rating table.
3.
The pick-up settings of the instantaneous and short time
delay elements are continuously adjustable, and are
calibrated at 3, 5, 8 and 12 multiples of the long time
pickup setting.
4. The Pick-up settings of the around elements are continu-
ously
