Product FAQs
7 answersWhat does the ST1 suffix indicate on this GE circuit breaker?
The ST1 suffix means this breaker includes a factory-installed 120V AC shunt trip. This allows the breaker to be opened remotely by an external control signal, such as an emergency stop or fire alarm interface.
How is the shunt trip wired on the THQL2130ST1?
The breaker includes factory-installed pigtail wires for the 120V AC shunt trip coil. These wires must be connected to your external control circuit to enable remote tripping.
What voltage is required to operate the shunt trip on this breaker?
The ST1 suffix indicates a 120V AC shunt trip coil. You must supply 120V AC to the shunt trip pigtail wires to remotely open the breaker.
Can I use the THQL2130ST1 in a bolt-on panelboard?
No. The THQL series features a plug-in mounting style. For GE A-Series or Spectra lighting panels that require bolt-on connections, you will need the equivalent THQB series breaker, such as the THQB2130ST1.
How much panel space does the THQL2130ST1 require?
This 2-pole breaker is 2 inches wide and requires two standard 1-inch spaces in a compatible GE load center. The factory-installed shunt trip is internal and does not require an additional pole space.
Are ABB and GE THQL2130ST1 breakers the same?
Yes. ABB acquired GE Industrial Solutions in 2018. The THQL2130ST1 is manufactured to the exact same specifications and fits the same panels, regardless of whether the label says GE or ABB.
Does this breaker include ground fault or arc fault protection?
No. The THQL2130ST1 is a standard thermal-magnetic breaker with a shunt trip. It does not provide GFCI or AFCI protection.
